Abstract
A radio frequency (RF) receiving coil assembly for a magnetic resonance imaging (MRI) system includes a plurality of loops. The RF receiving coil assembly also includes a plurality of electronics units, wherein a respective electronics unit of the plurality of electronics units is coupled to a respective loop of the plurality of loops, wherein each respective electronics unit includes circuitry configured to measure a temperature of the respective loop and to regulate power provided to the respective loop based on the temperature of the respective loop.
Claims20
A radio frequency (RF) receiving coil assembly for a magnetic resonance imaging (MRI) system, comprising:
- a plurality of loops;
- and
- a plurality of electronics units, wherein a respective electronics unit of the plurality of electronics units is coupled to a respective loop of the plurality of loops, wherein each respective electronics unit comprises circuitry configured to measure a temperature of the respective loop and to regulate power provided to the respective loop based on the temperature of the respective loop.
A system for regulating operation of a magnetic resonance imaging (MRI) system, comprising:
- a memory encoding processor-executable routines;
- and
- a processor configured to access the memory and to execute the processor-executable routines, wherein the routines, when executed by the processor, cause the processor to:
- monitor, during a scan by the MRI system, a radio frequency (RF) receiving coil assembly of the MRI system for a signal indicative of at least one loop of a plurality of loops of the RF coil assembly exceeding a threshold temperature, wherein each respective loop of the plurality of loops comprises circuitry configured to measure a temperature of the respective loop and to regulate power provided to the respective loop based on the temperature of the respective loop;
- and
- alter the scan of the MRI system upon receiving the signal indicative of the at least one loop exceeding the threshold temperature.
A magnetic resonance imaging (MRI) system, comprising:
- an imaging portion having a radio frequency (RF) receiving coil, wherein the RF receiving coil comprises a plurality of loops, wherein each respective loop of the plurality of loops comprises circuitry configured to measure a temperature of the respective loop and to deactivate the respective loop when the temperature of the respective loop exceeds a threshold temperature;
- and
- a controller configured to monitor, during a scan by the MRI system, the RF receiving coil assembly of the MRI system for a signal indicative of at least one loop of the plurality of loops exceeding the threshold temperature and to cease the scan or to alter the scan to a lower quality scan upon receiving the signal indicative of the at least one loop exceeding the threshold temperature.
