ABSTRACT:
Method for navigating a flexible medical device within a flexible organ of the body of a patient, toward a target region of interest of an inner wall of the flexible organ, by employing a previously acquired global three-dimensional (3D) model of the flexible organ, the method including the procedures of acquiring an initial stereoscopic image of an initial region of the flexible organ and reconstructing an initial local 3D model of the initial region according to the initial stereoscopic image, identifying and registering the initial local 3D model with an initial segment of the previously acquired global 3D model, acquiring a successive stereoscopic image of a successive region of the flexible organ and reconstructing a successive local 3D model of the successive region according to the successive stereoscopic image, identifying and registering the successive local 3D model with a successive segment of the previously acquired global 3D model, detecting the target region of interest by identifying a topography of the target region of interest according to the previously acquired global 3D model in the successive local 3D model, and producing a notification to indicate that the target region of interest is detected when the target region of interest is detected.
