MRI-guided catheter-based ultrasound thermal therapy of the prostate:
Real-time temperature image (left), maximum temperature image (middle), and thermal dose (right) of the prostate during catheter-based ultrasound thermal therapy. The transurethral catheter, with a rotating curvilinear transducer array, is depicted as the round low signal intensity structure within the prostate gland (69).
