Patent ID: 7495440

Claim:
A diffusion spectrum imaging, method, comprising the following steps: (A) obtaining a plurality of positions of sampling data in q-space using a regular non-rectangular sampling lattice in q-space to thereby obtain a series of diffusion weighted magnetic resonance images; and (B) arranging the series of diffusion weighted magnetic resonance images obtained in step (A) in q-space according to the regular non-rectangular sampling lattice for processing so as to obtain a probability density function; wherein step(A) includes the following sub-steps: (A-1) receiving a required sampling number and a range of sampling region in q-space set by a user; (A-2) obtaining a sampling interval by iteration using the regular non-rectangular sampling lattice when an actual sampling number converges to the required sampling number; and (A-3) obtaining the positions of the sampling data in q-space based on the sampling interval and the regular non-rectangular sampling lattice.
