1. A system for performing a sequence of ultrasound operations of an anatomic region in conjunction with MR imaging of the region, the sequence of ultrasound operations comprising at least one RF-sensitive operation and at least one RF-insensitive operation, the system comprising:
an MRI apparatus for imaging the anatomic region, the imaging comprising gradient field activity; and
an ultrasound controller in communication with the MRI apparatus, the ultrasound controller (i) initiating the RF-insensitive operation at any time during the MR imaging and (ii) initiating the RF-sensitive operation in response to a signal indicative of the gradient-field-activity suppression,
wherein the at least one RF-sensitive operation includes an operation associated with disturbance by RF excitement signals or the gradient-field-activity suppression, and the at least one RF-insensitive operation includes an operation which is not associated with disturbance by RF excitement signals or the gradient-field-activity suppression.
