Web30. sep 2024 · Diffusion-weighted MRI (DW-MRI) has recently seen a rising interest in planar, spherical and general B-tensor encodings. Some of these sequences have aided traditional linear encoding in the estimation of white matter microstructural features, generally by making DW-MRI less sensitive to the orientation of axon fascicles in a voxel. However, … WebRepresentation of response functions¶. The response functions required when performing spherical (de)convolution correspond to axially symmetric kernels (they typically represent the ideal signal for a coherently aligned bundle of fibres aligned with the \(z\) axis). Due to this symmetry, all \(m \neq 0\) coefficients can be assumed to be zero. . Therefore, … Web28. apr 2024 · matt77hias.

WebSpherical Harmonic bases. Spherical Harmonics (SH) are functions defined on the sphere. A collection of SH can be used as a basis function to represent and reconstruct any function on the surface of a unit sphere. Spherical harmonics are orthonormal functions defined by: Y m l (θ,ϕ) = √ 2l+1 4π (l−m)! (l+m)! P m l (cosθ)eimϕ Y l m ( θ ... WebEncode direction using spherical harmonics.
