Claim:
1. A magnetic resonance imaging (MRI) apparatus comprising: an assembly of MRI components including static and gradient magnetic field generators and at least one radio frequency (RF) coil defining an imaging volume; a computer system, connected to control said assembly of components, including at least one RF transmitter and at least one RF receiver, said computer system being configured to effect MRI scans including specified MRI data acquisition sequences of RF and gradient magnetic field pulses which produce nuclear magnetic resonance (NMR) spin responses emanating from different spatially located volumes of NMR nuclei as a function of a magnetic field experienced by the nuclei; said computer system being configured to control said assembly of MRI components to: repeat plural MRI scans on a heart of an object, detect a moving amount of a diaphragm due to respiratory movement of the object by executing a probe scan immediately before each of the MRI scans, and move an imaging range for each of the MRI scans based, in part, on the detected moving amount of the diaphragm by
