First Claim
Patent Images
1. A magnetic resonance imaging (MRI) apparatus comprising:
- a navigator device configured to use a navigator pulse sequence in the MRI apparatus to obtain information of body motion produced by respiration of a subject;
a respiration waveform display device configured to display a respiration waveform based on the body motion information obtained by the navigator device;
and an operating device configured for use by an operator to enter an instruction for operating the navigator device based at least in part on the respiration waveform.
