Title: MAGNETIC RESONANCE APPARATUS AND PROGRAM
Abstract:
A magnetic resonance apparatus comprising an 8-channel receive coil apparatus; a channel identifying unit for identifying, of the eight channels, four channels (CH1, CH2, CH5, and CH6) disposed near an edge E1 of a liver, and four channels (CH3, CH4, CH7, and CH8) disposed at positions away from the edge E1 of the liver; and a respiratory signal generating unit for determining a first feature quantity of a navigator signal received by the four channels (CH1, CH2, CH5, and CH6), and a feature quantity of the navigator signal received by the four channels (CH3, CH4, CH7, and CH8), and generating a respiratory signal for a subject based on the first feature quantity and second feature quantity. A method provides a technique of generating a body motion signal, such as a respiratory signal or a heartbeat signal, for a subject while suppressing as much as possible the noise during performance of sequences.
