摘要： A q-space sampling method includes: (a) receiving a required sampling number and a range of sampling region in q-space set by a user; (b) obtaining a sampling interval by iteration using a regular non-rectangular sampling lattice when an actual sampling number converges to the required sampling number; and (c) obtaining positions of sampling data in q-space based on the sampling interval and the regular non-rectangular sampling lattice. A diffusion spectrum imaging method using the q-space sampling method is also disclosed.
