摘要：
Wall thickness of a cavity is determined by inserting a catheter intocontact with a wall of a cavity in a body of a subject. The distal segmentof the catheter is provided with a contact force sensor and an ultra-soundtransducer. The transducer is actuated to acquire ultrasound reflectiondata from the wall of the cavity, and while the transducer is actuated,the catheter is reciprocated against the wall of the cavity and thecontact force measured between the catheter and the wall of the cavity.The reflection data is correlated with the contact force. A set of thecorrelatedreflection data having the highest correlation with the contactforce is identified. The tissue thickness between the inner surface andthe identified set of the reflection data is calculated according to thetime of flight therebetween.
