Bessel Fourier Orientation Reconstruction (BFOR): An analytical diffusion propagator reconstruction for hybrid diffusion imaging and computation of q-space indices

► Propose a new analytical diffusion propagator scheme called BFOR. ► Derive rotationally invariant q-space indices using BFOR, like Po, MSD, and GFA. ► Validate BFOR using HYDI-acquired datasets, both synthetic and in vivo. ► Compare BFOR to existing analytical diffusion propagator schemes, like DPI and SPFI. ► Explore ways to mitigate the effects of Gibbs ringing on propagator reconstruction.
