METHOD AND DEVICE FOR COLLECTING MAGNETIC RESONANCE SIGNAL AND MAGNETIC RESONANCE IMAGE PICKUP DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress a false image caused by the action of an image pickup object by making the order of selection of a trajectory random when successively collecting magnetic resonance signals along with plural radial trajectories through the center of a (k) space. SOLUTION: A gradient driving part 130 generates a gradient magnetic field by applying a driving signal to a gradient coil part 106, an RF driving part 140 transmits an RF exciting signal by applying a driving signal to an RF coil part 108, and a data collecting part 150 fetches a signal received by the RF coil part 108 and collects them as digital data. A control part 160 controls the gradient driving part 130 and the data collecting part 150 and performs data collection in random order in spite of the order of alignment of trajectories concerning the radial trajectories for one scan aligned in order at a fixed angle pitch within the angle range of 180 deg. on the (k) space.
