  • Patent number: 10069668
    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: 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.

  • Patent number: 9724166
    Abstract: A system for navigating a medical device is provided. In one embodiment, a magnetic field generator assembly generates a magnetic field. Position sensors on the medical device, on an imaging system and on the body generate signals indicative of the positions within the magnetic field. The generator assembly and reference sensors are arranged such that a correlation exists between them and the positions of the body and of a radiation emitter and a radiation detector of the imaging system. An electronic control unit (ECU) determines, responsive to signals generated by the sensors, a position of the medical device, a position of one of the radiation emitter and detector and a distance between the emitter and detector. Using this information, the ECU can, for example, register images from the imaging system in a coordinate system and superimpose an image of the device on the image from the imaging system.

  • Patent number: 9675302
    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.

  • Patent number: 9445745
    Abstract: A medical tool includes a location sensor at a distal end. While the tool is being maneuvered to a desired region of interest, a control unit records a first location reading obtained according to an output from the sensor when requested by a user, indicative of when a patient's anatomy constrains free movement of the tool in at least one degree of freedom. Once the tool has reached the region of interest, the control unit records a second location reading according to the sensor output indicative of a current location. A relaxation shape of the tool forms a shape constraint on the tool shape reconstruction. The control unit determines a reconstruction representing the current shape of the tool based on the positional constraints and the shape constraint. The reconstruction is graphically superimposed on an image of the region of interest.
