External trigger imaging method and apparatus in magnetic resonance inspection apparatus

摘要

An external trigger method in a magnetic resonance inspection apparatus includes the steps of inputting collectively imaging control data including an imaging portion of a subject, the kind of sequences, a time interval between the sequences and the number of times of repetition of the sequences, executing a pre-processing sequence corresponding to the imaging sequence set to be first executed, and checking whether the time interval until the start of the imaging sequence to be next executed is set to a predetermined value. The imaging sequence is started by an external trigger when the time interval is set to the indefinite value. The imaging sequence is started after the passage of the time of the predetermined value when the time interval is set to the predetermined value.
