- 'Experimentally induced cerebral aneurysms in rats: VII. Scanning electron microscope |
|
study. |
|
|
|
The luminal surfaces of experimentally induced cerebral aneurysms and the branching |
|
sites in the circle of Willis in rats were investigated by scanning electron microscopy. |
|
Gap formation at the junctions of the endothelial cells was one of the most obvious |
|
changes on the endothelial surface of the aneurysms. Many leukocytes were observed |
|
adhering to these gaps. Regressive changes of endothelial cells, such as balloonlike |
|
protrusions and craterlike depressions, were also found in the aneurysms. At the |
|
branching site, where cerebral aneurysms often develop, endothelial cells were |
|
disarranged, rounded, and varied in size. A deep groove was also found adjacent |
|
to the apex. The role of endothelial cells and leukocytes in the development of |
|
cerebral aneurysms is discussed.' |

- "1. Introduction {#sec1}\n===============\n\nAn outstanding characteristic of\ |
|
\ white matter (WM) is its fibrillar construction. WM consists of tightly packed\ |
|
\ and coherently aligned axons that are surrounded by glial cells and that often\ |
|
\ are organized in bundles \\[[@B1]\\]. Axons are protected by myelin sheaths,\ |
|
\ which restricts the free diffusion of water molecules. As a result, the micrometric\ |
|
\ movements of water molecules are hindered to a greater extent in a direction\ |
|
\ perpendicular to the axonal orientation than parallel to it. It is now generally\ |
|
\ accepted that microscopic boundaries to diffusion in WM coincide with the local\ |
|
\ orientations of WM fiber pathways \\[[@B2]--[@B4]\\]. With this feature, we\ |
|
\ can trace fiber pathways and then reveal anatomical connection between brain\ |
|
\ functional areas.\n \nCompared to diffusion tensor imaging (DTI), high angular\ |
|
\ resolution diffusion imaging (HARDI) could resolve multiple intravoxel fiber\ |
|
\ orientations contained in a WM voxel. Moreover, HARDI just needs to sample the\ |
|
\ diffusion signal on a spherical shell as opposed to a complete three-dimensional\ |
|
\ Cartesian grid of DSI \\[[@B5]--[@B7]\\]. At present, there are numerous tracking\ |
|
\ methods based on HARDI, which could be classified into deterministic and probabilistic\ |
|
\ algorithms \\[[@B8]\\ ]. They exploit the diffusion anisotropy to follow fiber\ |
|
\ tracts from voxel to voxel through the brain \\[[@B9]\\]. Recently, multishell\ |
|
\ multitissue (MSMT) models have been proposed to deal with partial volume effects\ |
|
\ and can remarkably increase the precision of fiber orientations over single-shell\ |
|
\ models \\[[@B10]\\].\n\n Streamline tracking is an important deterministic approach.\ |
|
\ Streamline tracking propagates paths within the vector field of local fiber\ |
|
\ orientations \\[[@B9]\\ ], providing deterministic connectivity information\ |
|
\ between different brain functional areas. Later, many variants of the streamline\ |
|
\ method have been presented. The streamline-based tracking technique is the one\ |
|
\ most commonly used in tractography, and it appears to give excellent results\ |
|
\ in many instances if the vector field is smooth and the fibers are strongly\ |
|
\ oriented along a certain direction. However, the major drawback of streamline-based\ |
|
\ methods is that the estimation error accumulates along the tracking length \\\ |
|
[[@B11], [@B12]\\]. However, the partial volume effects such as crossing, kissing,\ |
|
\ merging, and splitting in imaging voxels increase the complexity in streamline\ |
|
\ tracking.\n\nThere are also some nonstreamline tractography algorithms. In the\ |
|
\ graph-based method, each voxel is treated as a graph node, and graph arcs connect\ |
|
\ neighboring voxels. The weights assigned to each arc are the representative\ |
|
\ of both structural and diffusivity features \\[[@B13]\\]. When partial volume\ |
|
\ exists, the algorithm treats the image as a multigraph and distributes the connectivities\ |
|
\ in a weighted manner. Aranda et al. presented a particle method which was proposed\ |
|
\ to estimate fiber pathways from multiple intravoxel diffusion orientations (MIVDO)\ |
|
\ \\[[@B14]\\]. The process starts with the definition of a point in WM region\ |
|
\ in which a virtual particle is allocated. The particle is iteratively moved\ |
|
\ along the local diffusion orientations until a stopping criterion is met. The\ |
|
\ estimation of fiber pathways is determined by the particle trajectory. Galinsky\ |
|
\ and Frank proposed a method for estimating local diffusion and fiber tracts\ |
|
\ based upon the information entropy flow that computes the maximum entropy trajectories\ |
|
\ \\[[@B15]\\]. This novel approach to fiber tracking incorporates global information\ |
|
\ about multiple fiber crossings in each individual voxel. Malcolm et al. used\ |
|
\ Watson function to analyze ODF construction, which provides a compact representation\ |
|
\ of the diffusion-anisotropic signal \\[[@B16]\\]. This algorithm models the\ |
|
\ diffusion as a discrete mixture of Watson directional functions and performs\ |
|
\ tractography within a filtering framework. Recently, global tractography was\ |
|
\ proposed in \\ [[@B17]\\], which aims to find the full track configuration that\ |
|
\ best explains the measured diffusion weighted imaging (DWI) data. This data-driven\ |
|
\ approach was reported that it could improve valid neural connection rate over\ |
|
\ streamline methods.\n\nThe other classes are probabilistic approaches. This\ |
|
\ class of methods utilizes a stochastic process to estimate the connection probability\ |
|
\ between brain areas. A Bayesian approach was presented in \\[[@B18]\\], and\ |
|
\ it handled noise in a theoretically justified way. The persistent angular structure\ |
|
\ (PAS) of fiber bundles was used to drive probabilistic tracts, and PDF is incorporated\ |
|
\ into the method to estimate the whole-brain probability maps of anatomical connection\ |
|
\ \\ [[@B19]\\]. Using automatic relevance determination in a Bayesian estimation\ |
|
\ scheme, the tracking in a multivector field was performed with significant advantages\ |
|
\ in sensitivity \\[[@B20]\\]. The residual bootstrap method made use of spherical\ |
|
\ harmonic (SH) representation for HARDI data in order to estimate the uncertainty\ |
|
\ in multimodal q-ball reconstructions \\[[@B21]\\]. However, these methods cannot\ |
|
\ directly delineate the fiber paths in 3D brain space. Furthermore, they are\ |
|
\ very time consuming in resolving the complexity of the diffusion pattern within\ |
|
\ each HARDI voxel.\n\nIn \\[[@B22], [@B23]\\], the authors argued that NURBS\ |
|
\ provides a framework to characterize WM pathways. However, the determination\ |
|
\ of the parameters including control points and weights has not been discussed.\ |
|
\ This paper has comprehensively explored the tracking method based on NURBS curve\ |
|
\ fitting and has detailed how to determine the related parameters. The tracking\ |
|
\ method consists of three steps: first is the computation of ODF field from HARDI\ |
|
\ datasets; second is the selection of consecutive diffusion directions along\ |
|
\ a fiber pathway; and the last is NURBS pathway fitting. This method was evaluated\ |
|
\ on tractometer phantom and real brain datasets.\n\n2. Materials and Methods\ |
|
\ {#sec2}\n========================\n\n2.1. HARDI Datasets {#sec2.1}\n-------------------\n\ |
|
\nTwo different types of HARDI datasets are used to evaluate our approach: from\ |
|
\ the physical diffusion phantom of tractometer and from an in vivo human brain.\ |
|
\ For each dataset, we firstly constructed ODF fields using DOT method \\[[@B24]\\\ |
|
] and then applied the proposed algorithms to estimate fiber paths.\n\nPhantom\ |
|
\ study was performed using data acquired from a physical diffusion phantom of\ |
|
\ tractometer. Imaging parameters for the 3 × 3 × 3 mm acquisition were as follows:\ |
|
\ field of view FOV = 19.2 cm, matrix 64 × 64, slice thickness TH = 3 mm, read\ |
|
\ bandwidth RBW = 1775 Hz/pixel, partial Fourier factor 6/8, parallel reduction\ |
|
\ factor GRAPPA = 2, repetition time TR = 5 s, and echo times TE = 102 ms. A SNR\ |
|
\ of 15.8 was measured for the baseline (*b* = 0 s/mm^2^) image. SNR of HARDI\ |
|
\ at b-values = 2000 s/mm^2^ were evaluated. The diffusion sensitization was applied\ |
|
\ along a set of 64 orientations uniformly distributed over the sphere \\[[@B25]\\\ |
|
]. For comparative study, the ground truth fibers are available on the website\ |
|
\ <http://www.lnao.fr/spip.php?rubrique79> \\[[@B25]\\].\n\nA healthy volunteer\ |
|
\ was scanned on a Siemens Trio 3T scanner with 12 channel coils. The acquisition\ |
|
\ parameters were as follows: two images with *b* = 0 s/mm^2^, 64 DW images with\ |
|
\ unique, and isotropically distributed orientations (*b* = 2000 s/mm^2^). TR\ |
|
\ = 6700 ms, TE = 85 ms, and voxel dimensions equal to 2 × 2 × 2 mm. The SNR is,\ |
|
\ approximately, equal to 36.\n\n2.2. ODF Fields {#sec2.2}\n---------------\n\ |
|
\ \nCompared with diffusion tensor, ODFs reflect the diffusion probability along\ |
|
\ any given angular direction, and higher values indicate higher consistency between\ |
|
\ the fiber orientation and diffusion direction. ODFs can be seen as a continuous\ |
|
\ function over the sphere that encodes diffusion anisotropy of water molecules\ |
|
\ within each voxel. There are two definitions of ODF. One is Tuch\\'s nonmarginal\ |
|
\ ODF that is defined as the radial integration of PDF and does not represent\ |
|
\ a true probability density \\[[@B26], [@B27]\\]. The other is marginal ODF that\ |
|
\ is introduced by Wedeen, and it is a true probability density since its integral\ |
|
\ over the sphere is one \\[[@B28]\\]. ODF peaks are assumed to correspond to\ |
|
\ the underlying fiber orientations. At present, there are several algorithms\ |
|
\ to compute ODFs from HARDI datasets. Tuch presented a simple linear matrix formulation\ |
|
\ that was provided to construct ODFs using radial basic function (RBF) \\[[@B26]\\\ |
|
]. Diffusion orientation transform (DOT) converts water diffusivity profiles into\ |
|
\ probability profiles under the monoexponential signal decay assumption through\ |
|
\ computing PDF at a fixed distance from the origin \\[[@B24], [@B29], [@B30]\\\ |
|
\ ]. Spherical deconvolution (SD) estimates fiber orientations by assuming that\ |
|
\ a single response function can adequately describe HARDI signals measured from\ |
|
\ any fiber bundle \\[[@B31]\\]. Compared to other methods, DOT can improve the\ |
|
\ angular resolution, make the ODF sharper, and keep its accuracy and robustness\ |
|
\ to noise \\[[@B27], [@B30]\\]. In our work, we used DOT to construct ODFs from\ |
|
\ HARDI datasets.\n\nAfter ODF fields were constructed, we detected ODF local\ |
|
\ maxima by thresholding over the sampling shell. Only those above ODF mean value\ |
|
\ would be retained. This operation can avoid the noise interference effectively\ |
|
\ \\[[@B28]\\ ]. Finally, ODF fields are transformed into vector fields, and we\ |
|
\ can describe a voxel using a matrix containing diffusion vectors and its corresponding\ |
|
\ diffusion probability.$$\\begin{matrix}\n{V_{\\text{voxel}} = \\begin{bmatrix}\n\ |
|
{v_{1,x}\\ quad v_{1,y}\\quad v_{1,z}\\quad d_{1}} \\\\\n...... \\\\\n{v_{i,x}\\\ |
|
quad v_{i,y}\\ quad v_{i,z}\\quad d_{i}} \\\\\n...... \\\\\n{v_{n,x}\\quad v_{n,y}\\\ |
|
quad v_{n,z}\\ quad d_{n}} \\\\\n\\end{bmatrix}.} \\\\\n\\end{matrix}$$\n\nThe\ |
|
\ term $\\begin{bmatrix}\n v_{i,x} & v_{i,y} & v_{i,z} \\\\\n\\end{bmatrix}$ denotes\ |
|
\ a diffusion direction, and *d*~*i*~ is the diffusion probability along this\ |
|
\ orientation. In the next section, we would use this matrix to compute the control\ |
|
\ points and weights for NURBS pathway fitting.\n\n2.3. Diffusion Directions along\ |
|
\ a Fiber Pathway {#sec2.3}\n -----------------------------------------------\n\ |
|
\nBefore we conduct NURBS tracking, the consecutive directions along the same\ |
|
\ pathway have to be extracted. The orientations of fiber populations within a\ |
|
\ voxel coincide with the local maxima of ODFs \\ [[@B28]\\]. ODF value along\ |
|
\ a direction is the reflection of diffusion probability of all the water molecules\ |
|
\ in a voxel, so it is reasonable to assume that the diffusion directions always\ |
|
\ pass through the voxel center. The aim of this step is to find the consecutive\ |
|
\ directions among the neighbors of a seed voxel. Here, we presented a new algorithm\ |
|
\ to achieve the goal. For the sake of simplicity, we used a two-dimensional diagram\ |
|
\ as an example to illustrate the process, shown as [Figure 1(a)](#fig1){ref-type=\"\ |
|
fig\"}. Compared to FACT algorithm \\[[@B32]\\ ], it can improve the extraction\ |
|
\ accuracy of discrete consecutive directions along a pathway. As we can see from\ |
|
\ [Figure 1(b)](#fig1){ref-type=\"fig\"}, in FACT, an unreasonable path was found\ |
|
\ (marked by red dashed lines). But if the distance between V1 (blue line in the\ |
|
\ seed voxel) and the center points of its neighbor voxel is considered here,\ |
|
\ we could get a more reasonable pathway (marked by blue dashed lines in [Figure\ |
|
\ 1(b)](#fig1){ref-type=\"fig\"}). The algorithm is summarized as [Algorithm 1](#alg1){ref-type=\"\ |
|
fig\"}. The input parameters, including fiber length threshold *L*~th~, angle\ |
|
\ threshold *θ*~th~, and fractional anisotropy (FA) threshold *FA*~th~ should\ |
|
\ be determined according to actual situation.\n\n2.4. NURBS Fitting {#sec2.4}\n\ |
|
------------------\n\nNURBS is a powerful tool to describe complex curves using\ |
|
\ a small number of parameters. It is a wonderful modeling method of curves and\ |
|
\ can control the object more conveniently and efficiently than traditional modeling\ |
|
\ method \\[[@B33]\\]. The order of a NURBS curve defines the number of nearby\ |
|
\ control points that could influence any given point on the curve. In practice,\ |
|
\ cubic curves are the ones most commonly used. Higher order curves are seldom\ |
|
\ used because they may lead to internal numerical problems and require disproportionately\ |
|
\ large computation time \\[[@B34]--[@B36]\\]. The number of control points must\ |
|
\ be greater than or equal to the order of the curve. In this work, we traced\ |
|
\ nerve fiber pathways based on NURBS curve fitting. In the fitting, the parameters\ |
|
\ including control points and weights are needed. The consecutive directions\ |
|
\ were used to compute control points. The weights were computed according to\ |
|
\ *d*~*i*~. In NURBS tracking, we could use both control points and weights to\ |
|
\ hold local shape control of fiber pathways. We present two tracking methods\ |
|
\ based on NURBS according the fitting rule, including general NURBS fitting (NURBS-G)\ |
|
\ and tangent NURBS fitting (NURBS-T). The whole procedure of NURBS tracking is\ |
|
\ shown in [Figure 2](#fig2){ref-type=\"fig\"}.\n\n2.5. NURBS-T {#sec2.5}\n------------\n\ |
|
\ \nA fiber pathway can be considered as a 3D curve, and its local tangent vector\ |
|
\ is consistent with the diffusion orientation \\[[@B37]\\]. According to this\ |
|
\ premise, we presented NURBS-T algorithm to trace fiber paths. To make it easier\ |
|
\ to explain, the 2D tracking process is illustrated in [Figure 3](#fig3){ref-type=\"\ |
|
fig\"}. The algorithm is outlined in [Algorithm 2](#alg2){ref-type=\"fig\"}.\n\ |
|
\n2.6. NURBS-G {#sec2.6}\n------------\n\nIn NURBS-G tracking, we do not consider\ |
|
\ the tangent relationship between fiber pathway and diffusion direction. The\ |
|
\ control points consist of only intersection points between the diffusion directions\ |
|
\ and the facets of the voxel. The 2D tracking process is demonstrated in [Figure\ |
|
\ 4](#fig4){ref-type=\"fig\"}. The algorithm is outlined in [Algorithm 3](#alg3){ref-type=\"\ |
|
fig\"}.\n \n3. Results {#sec3}\n==========\n\n[Figure 5](#fig5){ref-type=\"fig\"\ |
|
} shows the ODF and vector fields estimated from HARDI images of tractometer.\ |
|
\ Panel (a) is the mask of fiber pathways. We extracted the diffusion directions\ |
|
\ corresponding to ODF local maxima that are above the mean value of ODFs. Through\ |
|
\ this filtration, spurious peaks could be effectively reduced \\[[@B28]\\].\n\ |
|
\nAfter the vector fields were obtained, the control points and weights were computed.\ |
|
\ Next, the fiber pathways were traced with multidirectional streamline, NURBS-T,\ |
|
\ and NURBS-G. In this phantom experiment, *θ*~th~ is set to 60° and *L*~th~ is\ |
|
\ 70 mm. *FA*~th~ was not set for this test, as WM mask was provided in tractometer\ |
|
\ dataset. [Figure 6(a)](#fig6){ref-type=\"fig\"} shows 16 seed points selected\ |
|
\ according to \\[[@B25]\\ ], and [6(b)](#fig6){ref-type=\"fig\"} shows the ground\ |
|
\ truth fiber pathways. Figures [6(c)](#fig6){ref-type=\"fig\"}, [6(d)](#fig6){ref-type=\"\ |
|
fig\"}, and [6(e)](#fig6){ref-type=\"fig\"} show the tracking results.\n\nIn order\ |
|
\ to evaluate the proposed algorithms, two kinds of measure methods were taken.\ |
|
\ One is the point-to-point performance measures; the other is the connection\ |
|
\ measures. The former includes spatial metric (SM), tangent metric (TM), and\ |
|
\ curve metric (CM) \\[[@B25]\\]. These metrics focus on the point-to-point performance\ |
|
\ from a local perspective. The latter contains valid connections (VC), invalid\ |
|
\ connections (IC), no connections (NC), valid bundles (VB), and invalid bundles\ |
|
\ (IB) \\[[@B39]\\]. From a global point of view, the connections generated by\ |
|
\ the estimated trajectories are relevant. The set of global metrics takes into\ |
|
\ account the resulting connectivity. In this experiment, we evaluated the results\ |
|
\ with both local and global metrics. Figures [7](#fig7){ref-type=\"fig\"}[](#fig8){ref-type=\"\ |
|
fig\"}--[9](#fig9){ref-type=\"fig\"} show the summation of the points per metric\ |
|
\ for each method. [Table 1](#tab1){ref-type=\"table\"} shows the evaluation by\ |
|
\ using the global metrics: VC, IC, NC, VB, and IB.\n\nWe can come to that for\ |
|
\ the spatial metric NURBS-T obtains the best score except Fiber 3 and 10. For\ |
|
\ the tangent metric, NURBS-T also gets the best position except Fiber 10. For\ |
|
\ the curve metric, NURBS-T obtains the best place except for Fiber 9 and 15.\ |
|
\ Summarizing the overall performance over the three metrics, we can conclude\ |
|
\ that NURBS-T is best on the fiber pathway estimation of the phantom. For the\ |
|
\ computation time, NRBS-T recovered the previous results in about 23 minutes,\ |
|
\ and NURBS-G took about 20 minutes. The method of multidirectional streamline\ |
|
\ required 27 minutes or so to complete the task at the step of 0.02 mm. These\ |
|
\ methods were all implemented in Matlab R2014b running on the computer possessing\ |
|
\ 8G RAM and Intel Core i5-7200U.\n\nFrom the above analysis, NURBS-T presents\ |
|
\ competitive results for both kinds of measure metrics. Furthermore, we used\ |
|
\ the mask ([Figure 5](#fig5){ref-type=\"fig\"}) to evaluate the resulting connectivity.\ |
|
\ The values in [Table 1](#tab1){ref-type=\"table\"} show that the method with\ |
|
\ the best performance is NURBS-T.\n\nFigures [10](#fig10){ref-type=\"fig\"}[](#fig11){ref-type=\"\ |
|
fig\"}--[12](#fig12){ref-type=\"fig\"} show the estimated fibers of the in vivo\ |
|
\ human brain data. In this in vivo experiment, *θ*~th~ is 60° and *L*~th~ is\ |
|
\ 70 mm. *FA*~th~ is 0.15. We selected three ROIs to trace fiber pathways. The\ |
|
\ ROI in [Figure 10](#fig10){ref-type=\"fig\"} is located in the region of corpus\ |
|
\ callosum. The ROI in [Figure 11](#fig11){ref-type=\"fig\"} lies in the region\ |
|
\ of parietal lobe. The ROI in [Figure 12](#fig12){ref-type=\"fig\"} is in the\ |
|
\ region of bilateral mesial temporal lobes. As there is no golden standard of\ |
|
\ fiber distribution map with high resolution, we can only qualitatively analyze\ |
|
\ the results.\n\nFrom [Figure 10](#fig10){ref-type=\"fig\"}, we can easily pick\ |
|
\ out two fake fiber bundles that are marked by brown arrows. The thin bundle\ |
|
\ pointed by the left arrow is obviously nonexistent in the region of corpus callosum.\ |
|
\ The pathway pointed by the right arrow is unreasonable since it should not spread\ |
|
\ along the vertical direction. In [Figure 10](#fig10){ref-type=\"fig\"}, from\ |
|
\ the morphological perspective, the fiber bundles are excessively messy and fluffy\ |
|
\ in the regions pointed by the two arrows because there are fewer constraints\ |
|
\ on the NURBS-G fitting. In Figures [11](#fig11){ref-type=\"fig\"} and [11](#fig11){ref-type=\"\ |
|
fig\"}, there are too many crossing bundles, which disorderly emerge into the\ |
|
\ edge of WM in the region marked by arrows. In [Figure 12](#fig12){ref-type=\"\ |
|
fig\"}, some unreasonable bundles could be found as their pathways spread out\ |
|
\ WM region. From [Figure 12](#fig12){ref-type=\"fig\"}, we could see there are\ |
|
\ some minor bundles winds around the main bundles in the region pointed by the\ |
|
\ up-down arrow. In addition, the existence of the bundles in the regions pointed\ |
|
\ by the other three arrows is unreasonable.\n\nFrom these in vivo tracking results,\ |
|
\ we can qualitatively validate our method. At last, to quantitatively analyze\ |
|
\ the proposed methods, we compared the results in the aspects of number of bundles,\ |
|
\ computation time, and storage ([Table 2](#tab2){ref-type=\"table\"}). The fiber\ |
|
\ bundles were stored as .mat file in Matlab 2014b. These methods were evaluated\ |
|
\ on the computer possessing 8G RAM and Intel Core i5-7200U CPU.\n\n4. Discussion\ |
|
\ {#sec4}\n=============\n\nIn the presented study, we developed a novel tracking\ |
|
\ method based on NURBS curve fitting. The method consists of two steps. The first\ |
|
\ is to obtain the consecutive diffusion directions along a fiber pathway. The\ |
|
\ second is to carry out NURBS curve fitting. For the first step, we proposed\ |
|
\ a more effective way to find the consecutive vectors for a seed voxel among\ |
|
\ its 26-connected voxels. The comparison to FACT is shown in [Figure 1](#fig1){ref-type=\"\ |
|
fig\"}. In the second step, the control points were obtained according to the\ |
|
\ equation given in the [Algorithm 2](#alg2){ref-type=\"fig\"}. The corresponding\ |
|
\ weights are computed according to the equation given in the [Algorithm 2](#alg2){ref-type=\"\ |
|
fig\"}. From the experimental results, we can conclude that the proposed method\ |
|
\ is well suited for exploring WM pathways.\n\nThe proposed method aims to reveal\ |
|
\ the connectivity among brain function areas. It is important to realize that\ |
|
\ our method does depend heavily on the parameters of control points and weights.\ |
|
\ Although we presented here both the theoretical foundation and a number of practical\ |
|
\ examples that characterize performance and accuracy of our approach, the main\ |
|
\ limitation of our work is the lack of a system wide analysis of the two parameters\ |
|
\ that can influence the fitting results. In NURBS fitting, we would continue\ |
|
\ to study the mathematical relationship between the weights and ODF peaks.\n\n\ |
|
In general, there are two main factors influencing the tracking results: the noise\ |
|
\ in HARDI images and partial volume effects \\ [[@B40]\\]. The noise could cause\ |
|
\ the inconsistency, and the incomplete information about partial volume effect\ |
|
\ could confuse the tacking process. In consequence, some fiber paths are incorrectly\ |
|
\ estimated \\[[@B6]\\]. Before the construction of ODF fields, we used NLPCA\ |
|
\ to denoise HARDI dataset. In the regions of fiber crossing, branching, and merging,\ |
|
\ the multiple compartments within a voxel make it hard to find out the fiber\ |
|
\ orientation from ODF fields for such entangled structures. In fact, the sensitivity\ |
|
\ to detect multiple fiber populations depends not only on the datasets but also\ |
|
\ on specifics of the construction technique of ODF. If the resolution capability\ |
|
\ of the construction method is low, the deviation between ODF maxima and the\ |
|
\ ground truth directions would become large. This error can limit the fiber tracking\ |
|
\ technique to fully delineate a fiber tract.\n\nAnother important factor that\ |
|
\ can influence the tracking results is stop criteria. FA could not be considered\ |
|
\ as one of the tracking stop criteria because FA is generally less than 0.2 in\ |
|
\ a voxel with crossing fibers \\[[@B40]\\]. Except for that, we considered the\ |
|
\ fiber length and the angle as stop criteria. However, validation of fiber tractography\ |
|
\ remains an open question \\[[@B25]\\].\n\n5. Conclusion {#sec5}\n=============\n\ |
|
\nAnatomical connectivity network is important to the investigation of human brain\ |
|
\ functions. The quality of anatomical connectivity relies on proper tract estimation\ |
|
\ \\[[@B6]\\]. In this work, we presented a novel algorithm based on NURBS curve\ |
|
\ fitting. The proposed methods exhibit promising potential in exploring the structural\ |
|
\ connectivity of human brain. They are easily implemented and proved efficient\ |
|
\ through phantom and real experiments. However, it is still difficult to identify\ |
|
\ the fiber bundles that are diverging, converging, and kissing. In future, our\ |
|
\ study will be mainly focused on how to solve this problem with NURBS fitting.\ |
|
\ More anatomical constraints should be used to guide tracking processes.\n\n\ |
