Abstract
A spin in a predetermined voxel of the brain surface is excited to cause the spin to perform steady state free precession which causes signals, of which a time-reversed FID signal relating to spin-spin relaxation time T2 is enhanced to form an image representative of a thickness of cerebrospinal fluid existent in the brain surface, that is, of a brain surface structure. The spin can be caused to perform the steady state free precession by applying a pulse at the rate of a short repetition time and therefore an image of the brain surface can be obtained within a short period of time.
