FOCUSED ULTRASOUND SYSTEM WITH MRI SYNCHRONIZATION

摘要

A MRI system (50) uses a timing sequence for transmitting radio frequency (RF) signals and detecting magnetic resonance (MR) response signals from a patient's body in response to the RF pulse sequences. A piezoelectric transducer (14) is driven with drive signals such that the transducer emits acoustic energy towards a target tissue region (42) within the patient's body (40). Parameters of the drive signals are changed at times during the timing sequence that minimize interference with the MRI system detecting MR response signals, e.g., during transmission of RF signals by the MRI system.
