MAGNETIC RESONANCE IMAGING SYSTEM AND PROCESSING METHOD FOR MAGNETIC RESONANCE IMAGING GATHERING DATA

摘要

PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging system capable of displaying confirmation images for confirming the propriety of photographing in a shorter period of time in high-speed contrast MRA photographing by a PI method, and the processing method for magnetic resonance imaging gathering data. SOLUTION: The magnetic resonance imaging system comprises: a sensitivity map data base 51 for preserving the sensitivity map data of a multi-coil composed of a plurality of coils necessary for a parallel imaging expansion processing; a data segmentation means 40 for segmenting partial data from three-dimensional volume data gathered for the respective coils by parallel imaging photographing, respectively; an intermediate image reconstitution means 41 for reconstituting intermediate images for the respective coils by executing a reconstituting processing to the partial data; and a reference image generation means 42 for segmenting the sensitivity map data corresponding to the intermediate images from the sensitivity map data base as the sensitivity map data for an expansion processing, executing the parallel imaging expansion processing to the intermediate images by using the sensitivity map data for the expansion processing and generating reference images.
