Abstract: In a method and magnetic resonance (MR) apparatus for heart diffusion imaging, when an ECG trigger signal by a computer that operates an MR scanner, the MR scanner is operated to acquire a navigator echo before a stimulated echo sequence, in order to detect diaphragm position information. When the first diaphragm position information is not located in an acquisition window, the stimulated echo sequence is not executed, and the computer waits to receive the next ECG trigger signal. The detection time of the navigator echo after the stimulated echo sequence as well as the acquisition time of the stimulated echo sequence, are thus eliminated when the first diaphragm position information does not meet requirements, so can significantly reduce scanning time, and increase the image SNR.

Abstract: In a magnetic resonance coil selection method and selection computer, a range parameter of a target region (ROI) to be detected is acquired, and a detection range parameter of each available coil is acquired. A coil having a detection range that overlaps with a range of the ROI is determined and then selected. The selected coil is then used in the operation of a magnetic resonance scanner to acquire magnetic resonance data. The SNR of the magnetic resonance scanner is thereby increased, so as to improve the imaging quality.
