Diaphragm position can be accurately estimated from the scattering of a parallel transmit RF coil at 7 T.
To evaluate the use of radiofrequency scattering of a parallel transmit coil to track diaphragm motion.
Measurements made during radiofrequency excitation on an 8-channel parallel transmit coil by the directional couplers of the radiofrequency safety monitor were combined and converted into diaphragm position. A 30-s subject-specific calibration with an MRI navigator was used to determine a diaphragm estimate from each direct...
