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 a concurrently operated system include the steps of performing an MR scan sequence with the concurrently operated system idle; detecting intervals during the MR scan sequence when an RF level is sufficient to interfere with the RF-sensitive measurement storing data indicative of a temporal extent of the MR scan sequence and the detected intervals; and based at least in part on the stored data, simultaneously performing the scan sequence and operating the concurrently operated system but obtaining the RF-sensitive measurement only during times not corresponding to the recorded intervals.
