The implementation of MRI reconstruction algorithms based on a multi-core DSP (TMS320C6678) is described in this paper. As a state-of-the-art device, TMS320C6678 has powerful computing capability and high data throughput. The tasks of Fourier reconstruction and image combination (sum-of-squares) of multi-channels are assigned to different cores of the DSP; K-space data import, data processing and...
Grating phase-contrast CT obtains differential phase, which is different from conventional CT (absorb-contrast CT). How to retrieve phase of object becomes a new topic. Nowadays, many algorithms have appeared to retrieve and reconstruct materials' phase information. We design a new filter to retrieve phase but not increase the dose of X-ray. The result of phase retrieved shows the validity and correctness...
