摘要
Tracking of crossing WM fiber bundles can be resolved using diffusion MRI imaging. DTI can only resolve a single fiber orientation within each voxel due to the constraints of the tensor model. DSI requires large pulsed field gradients and time-intensive sampling. This paper puts forward with a new method based on QBI, which uses a spherical tomographic inversion called Funk-Radon transform to get high angular resolution diffusion imaging signal. From the tracking results, we can get the conclusion that QBI-tracking can resolve crossing fiber time-savingly.
