Title:
MAGNETIC RESONANCE IMAGING DEVICE, CALCULATION DEVICE FOR GENERATION OF IMAGING PARAMETER SET, AND IMAGING PARAMETER SET GENERATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/087543
Kind Code:
A1
Abstract:
This magnetic resonance imaging (MRI) device performs, at least three times in the same imaging sequence, imaging with different combinations of at least a repetition time and a flip angle, wherein the MRI device comprises: a reception unit that receives information specifying an imaging target and a constraint condition related to an imaging time or quantitative value accuracy; and an imaging parameter set generation unit that calculates, on the basis of the constraint condition, at least three imaging parameter sets having different combinations of at least the repetition time and the flip angle. The MRI device performs imaging multiple times using the at least three imaging parameter sets generated by the optimal imaging parameter set generation unit, and calculates a quantitative value (T1, T2, etc.) of the imaging target from the multiple images obtained by the imaging. Due to this configuration, the imaging parameters in quantitative value measurement can be easily set.
