This study describes development of an endocavitary probe comprising an MR compatible HIFU transducer integrated with an MR receiver coil for MR guided thermal ablation. The ability to produce phase images capable of detecting small (<5 deg C temperature rises) was demonstrated. Implementation of local shimming optimizes this.
