Abstract
MRI interference with a concurrently operated system may be reduced or corrected by subtracting the MRI interference from signals measured using the concurrently operated system. Various approaches for performing MRI of an anatomic region in conjunction with a radio-frequency-sensitive (RF-sensitive) measurement of the region using the concurrently operated system include the steps of simultaneously performing an MR scan sequence including MR pulses and the RF-sensitive measurements; recording the RF-sensitive measurements as they are made; detecting intervals during the MR scan sequence when an RF level is sufficient to interfere with the RF-sensitive measurements; and retaining only the RF-sensitive measurements performed outside the detected intervals.
