ratio (SNR) of the radio frequency (RF) receive coil array is a critical factor
affecting the accuracy of temperature measurement in MR-guided high-intensity focused ultrasound (HIFU)
for local heating. In this work, a flexible 11-channel coil array was designed,
constructed and evaluated for MR-guided HIFU studies on rabbit leg muscle at a
3 T MRI scanner. Compared to a commercial available 4-channel flexible coil
array, the dedicated 11-channel coil array provides improved performance in
SNR, parallel imaging capability, and the accuracy of temperature measurement.
