Abstract: A system for superimposing virtual anatomical landmarks on an image includes a medical positioning system (MPS) for producing location readings with respect to points within a region of interest in accordance with an output of a location sensor disposed in a medical device. A coordinate system of the MPS is registered with an image coordinate system. A control unit receives a signal from a user to record a location reading when the medical device is at a desired point in the region of interest where the user desires to place a virtual landmark, modifies the recorded location reading for motion compensation, transforms the motion-compensated location reading from the MPS coordinate system to the image coordinate system to produce a target location, and then superimposes a representation of the virtual landmark on the image at the target location.

Abstract: An apparatus for displaying a moving region of interest located within a body includes a positioning system to determine a position and orientation (P&O) of a medical device as well as to track, using an internal position reference sensor, the motion of the region of interest over time. A compensation function block generates a motion compensation function based on the motion of the region of interest, which is configured to compensate for the motion of the region of interest between a first time, for example a time at which an image was acquired and a second time, for example a time at which a P&O of the device was measured. The measured P&O is corrected using the compensation function. A representation of the medical device is superimposed on the image in accordance with the corrected P&O.

Abstract: Systems and methods are disclosed for navigating a surgical device toward a target organ in the body of a patient. An example method includes providing a surgical needle and a guide wire, the surgical needle configured for insertion into a vein or a beating heart. The method also includes holding the guide wire within the surgical needle while the surgical needle is inserted into the vein or the beating heart. The method also includes generating output in two modes, the output based on at least one medical positioning system (MPS) sensor on the guide wire, the output corresponding to a position of the surgical needle and the guide wire for navigating the surgical needle and the guide wire toward a target in the vein or the heart. The methods can be carried out directly by a physician or via a computer processor-based surgical system.

Abstract: A tool dislodgement detection apparatus includes an MPS outputting position and orientation (P&O) readings for determining tool motion. A control generates an alarm based on the tool motion and dislodgement criteria. The criteria includes whether the tool motion meets a condition based on the type of medical procedure or tool, the tool parking position, a patient characteristic (e.g., age, weight, gender) or a physician preference. The criteria includes when the correlation between the tool motion and the cardiac, respiration and patient motion changes abruptly. In a prolapse detection apparatus, guidewire tip P&O readings determine a tip motion vector. The control generates an alarm using the motion vector and predetermined criteria. The criteria include a substantial change in the tip orientation not accompanied by a corresponding position change and a change in the motion vector by about 180° accompanied by a corresponding position change no greater than a threshold.
