Abstract: A registration fixture is configured for use with a medical imaging system. The registration fixture comprises a rigid internal structure comprising a plurality of fiducial markers arranged in a predefined pattern. The registration fixture further comprises a housing configured to surround the rigid internal structure. The registration fixture is configured to be mounted on a patient table.

Abstract: Aspects of the present disclosure are directed to apparatuses for generating a magnetic field for tracking of a target object. Such an apparatus may include a localized magnetic field transmitter that generates a magnetic field and exhibits minimal X-ray absorption when used in proximity to a fluoroscopic imaging system, for example.

Abstract: 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.

Abstract: Various embodiments of the present disclosure identify and correct for magnetic field distortions within a magnetic field for localization of a medical device within a patient. Such magnetic field distortions, often associated with the intrusion of a metallic object into the magnetic field, may cause an unacceptable level of localization error which aspects of the present disclosure correct for.

Abstract: A radiation detection system comprises a scintillator for converting radiation to visible light; two buttable CMOS wafers; an adjacent acquisition board, for acquiring pixel values; and a processing board for detecting image edge is described. The butt of each adjacent CMOS wafers pair is made such that the total width of two peripheral pixel lines and the spacing between them sums to a whole number of pixel pitch.

Abstract: A radiation detection system is provided comprising a scintillator capable of converting the radiation to visible light; at least two buttable CMOS wafers; an adjacent acquisition board, for acquiring pixel values; and at least one processing board capable of image edge detection.

Abstract: An apparatus and method for radiation detection is herein described. The apparatus consists of two radiation-detection arrays: A primary radiation-detection array, based on scintillator-CMOS design, and a secondary radiation-detection array, mounted on the back of said primary array. A method of controlling the detection operation is described, where output of the secondary array is exploited for controlling the acquisition-start and acquisition-stop of the primary array. Further, the apparatus is equipped with fast memory for storage of correction tables, and with a processor for fast computation of the correction. A method of calibration is also describes with tables for: offset correction, gain correction, and for defect-pixel correction. These tables are evaluated by the fast processor and stored on the fast memory. A method of real-time evaluation of the signal corrections is described, which depends on the acquisition-start and acquisition-stop timings and which results a clean, artifact-free image.
