#$%^&*AU2015268763A120160714.pdf#####ABSTRACT Wall thickness of a cavity is determined by inserting a catheter into contact 5 with a wall of a cavity in a body of a subject. The distal segment of the catheter is provided with a contact force sensor and an ultrasound transducer. The transducer is actuated to acquire ultrasound reflection data from the wall of the cavity, and while the transducer is actuated, the catheter is reciprocated against the wall of the cavity and the contact force measured between the catheter and the wall of the t0 cavity. The reflection data is correlated with the contact force. A set of the correlated reflection data having the highest correlation with the contact force is identified. The tissue thickness between the inner surface and the identified set of the reflection data is calculated according to the time-of-flight therebetween. 17 of 172/4 13-1 41 49 37'. 1,, 43 3 6.11 Fi'G. 2 6 3 Contact Fa'rce Ti Uweof-filih 69) FIG. 3
