Abstract

A plurality of sensors (110) are disposed at least adjacent to portions of a flexible body (100) such as a catheter or endoscope that can be inserted into a cavity (123). Each sensor (110) is capable of sensing at least five degrees of freedom for the point of the flexible body (100) to which it is attached. A computing device (115) operatively connected to the plurality of tracking sensors (110) receives signals from the sensors (110) such that the computing device (115) may determine a shape and/or visualization (130) of the flexible body (100) and overlay it with various images of at least a portion of the cavity (123). The sensed portions of the flexible body (100) may be used to automatically determine the portions of the cavity (123) to image.
