In this work we evaluate a newly developed catheter-based therapeutic ultrasound (US) probe used for interstitial MR-guided high intensity focused US (iMRgFUS) procedures. Specifically, we optimize and down-select MR thermal imaging protocols in order to achieve maximum temperature measurement precision and volume coverage in the presence of image artifacts arising from the iMRgFUS probe design and operation.
