Abstract: An X-ray computed tomography (CT) scanner includes a plurality of X-Ray sources and detectors mounted about an opening where scanning takes place. The X-Ray sources and detectors are arranged to oscillate back and forth in opposing first and second rotational directions about the opening, or in the same rotational direction about the opening, in order to generate a cross-sectional image of an object located within the opening.

Abstract: Methods and systems are provided for additive manufacturing of collimators for medical imaging applications. In one example, a collimator may include a plurality of collimator segments including a plurality of septa, wherein at least one collimator segment may be interlocked with at least one adjacent collimator segment via mating of one or more projections with one or more complementary recesses, each of the one or more projections including a lengthwise portion of at least one septum of the plurality of septa.

Abstract: A radiation detector assembly is provided that includes a plurality of multi-detector arms (e.g., between 2 and 5), and plural detector head units disposed in each multi-detector arm. Each of the multi-detector arms defines a cavity therein. At least two detector head units are disposed within the cavity of each multi-detector arm. Each detector head unit includes an absorption member and associated processing circuitry, with the processing circuitry configured to generate electronic signals responsive to radiation received by the absorption member. Each detector head unit is configured to pivot along a sweep direction.

Abstract: A diagnostic imaging system and method using multiple types of imaging detectors are provided. The imaging system includes a gantry having a rotor and a stator and a pair of gamma detectors coupled to the rotor. The imaging system further includes a gamma detector coupled to the stator, The gamma detector coupled to the stator is different than the pair of gamma detectors coupled to the rotor.

Abstract: A nuclear medicine diagnostic imaging system wherein the gamma camera rotates about the patient and is coupled to receive electrical power, control signals and to transmit data using cableless coupling means. This enables the system to provide whole body helical scans. Reconstruction begins during the first revolution of the camera about the patient and continues during subsequent revolutions to provide evolving images.
