SYSTEMS AND METHODS FOR AVOIDING MRI-ORIGINATED INTERFERENCE WITH CONCURRENTLY USED SYSTEMS

摘要

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.

1. A method of performing magnetic resonance (MR) imaging of an anatomic region in conjunction with a radio-frequency-sensitive (RF-sensitive) measurement of the region using a concurrently operated system, the method comprising the steps of:
with the concurrently operated system idle, performing an MR scan sequence including MR pulses; detecting intervals during the MR scan sequence when an RF level is sufficient to interfere with the RF-sensitive measurements; storing data indicative of a temporal extent of the MR scan sequence and the detected intervals thereduring; 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 measurements only during times not corresponding to the recorded intervals.
