Title:
MAGNETIC RESONANCE IMAGING APPARATUS AND IMAGE GENERATION METHOD
Document Type and Number:
Japanese Patent JP2022045474
Kind Code:
A
Abstract:
To accurately remove noise of a separation image obtained by separating spatially-overlapping signals by using a PI method in an image acquired by radial sampling by using a plurality of reception coils using MRI.SOLUTION: A magnetic resonance imaging apparatus measures complex blade images that spatially overlap each other for each blade by radial sampling from nuclear magnetic resonance signals received by a plurality of reception coils, calculates a blade image by separating spatially-overlapping signals for each blade by using sensitivity information of the plurality of reception coils, and removes noise mixed into the blade image by repetition calculation on the basis of a g-factor map expressing noise characteristics for each blade.SELECTED DRAWING: Figure 5
