摘要： An apparatus for generating a magnetic field for tracking of an object can include a localized magnetic field generator that is configured to generate a magnetic field and to control the magnetic field in an area of interest and configured to control the magnetic field in a separate area. The separate area can be displaced from the area of interest and can include a magnetic field-disrupting component. The object can be located in the area of interest.

摘要： A registration fixture or plate is configured for use with a medical imaging system. The registration fixture may be an optical magnetic registration plate including a plurality of fiducial markers in arranged in a predefined unique pattern. The pattern can be unambiguously detected on 2D image of the plate produced by the medical imaging system. Association of the 2D imaged pattern of fiducial markers with the actual 3D pattern on the optical magnetic registration plate allows for accurate calculation of projection matrices and co-registration of the 3D and 2D coordinate systems.

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 magnetic field generator assembly is configured to be associated with a table supporting a body. The magnetic field generator comprises magnetic field transmitters that are thin (of minimal height) and transparent, or substantially transparent, to x-ray radiation. The magnetic field transmitters are configured to minimally obstruct components of an imaging system and to minimally interfere with image quality.

摘要： A magnetic field generator assembly is configured to be associated with a table supporting a body. The magnetic field generator comprises a plurality of magnetic field transmitters, each comprising interlacing layers of conductive material, configured to provide increased magnetic strength and minimal fluoroscopic occlusion. The interlacing layers of conductive material can be arranged in rectangular spiral formations.
