1. A method for treating a patient comprising:
a) inserting a cryoprobe within an introducer canula into targeted tissue in the patient;
b) generating an ice ball by cooling the cryoprobe;
c) removing the cryoprobe from the introducer canula and inserting an ultrasound catheter within the introducer canula; and
d) using the ultrasound catheter to determine a distance between the ultrasound catheter and a periphery of the ice ball by generating ultrasound energy within the ice ball.
