Abstract: A system and method for producing an image indicative of characteristics of a radiofrequency (“RF”) coil with a magnetic resonance imaging (“MRI”) system is disclosed. The method includes acquiring MR signals while performing a pulse sequence with the MRI system and driving the RF coil at a selected transmission power. This process is repeated a plurality of times to drive the RF coil at a different transmission powers during each repetition. A plurality of images are reconstructed from the acquired MR signals and an image indicative of RF reception characteristics of the RF coil is produced from the reconstructed images. Subsequently, an image indicative of RF transmission characteristics of the RF coil is produced using the image indicative of the RF receiver response. More specifically, only one data acquisition is necessary for each RF coil element to produce the image indicative of the RF transmission characteristics for that coil element.

Abstract: A system and method for selectively operating an array of RF receive coils in a transmit mode is disclosed. The system includes an RF transmit coil configured to generate an RF field that excites nuclei of a subject to generate RF resonance signals, an array of RF receive coils to receive the RF resonance signals, and a detuning circuit coupled to each RF receive coil in the array of RF receive coils that is selectively switched between a disabled and an enabled state to control a resonance and impedance of the RF receive coil. Each RF receive coil is caused to receive RF resonance signals when its respective detuning circuit is in the disabled state and is caused to modify an amplitude and phase of the RF field generated by the RF transmit coil when its respective detuning circuit is in the enabled state.
