    摘要: A system for registering a group of images of an anatomical region of a patient in a coordinate system of a medical system is disclosed. The system includes an object disposed in a known position in the coordinate system. In one embodiment, the object has a first state in which the object is visible in at least one image and a second state in which the object is invisible in at least another image. In another embodiment, the object is substantially invisible to the eye in each image, but detectable by image processing. The system includes an electronic control unit configured to process the images to identify an image location of the object, create a transformation model responsive to the image location and the known position of the object in the coordinate system, and register the group of images in the coordinate system using the model.

    摘要: 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.

    摘要: A roll-detecting sensor assembly includes a coil extending along and disposed about an axis. The coil comprises one or more portions, with each portion defining a winding angle. At least one of the portions defines a winding angle that is substantially nonzero relative to a line perpendicular to the axis, whereby the projected area of the coil in an applied magnetic field changes as the coil rotates about the axis. As a result, the coil is configured to produce a signal responsive to the magnetic field indicative of the roll of the sensor about the axis. In an embodiment, at least one of the portions defines a winding angle that is at least 2 degrees. In an embodiment, at least one of the portions defines a winding angle that is about 45 degrees.

    摘要: 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.
