In this study, we evaluated how the Cardiac MRI positioning assist function can reduce the operation steps and times in CMRI. When using the assist function, the total number of the operation steps was reduced to about 25% for both the experts and the beginners. The operation time was also reduced to about 25%. The mean and SD of the elapsed time for the CMRI procedure performed by experts were reduced from 42m17s±10m53s to 32m46s±3m29s, and those for coronary angiography were reduced from 20m42s±8m5s to 15m22s±2m49s.
