摘要： Scanning systems may include a stator, a rotor supporting at least one radiation source and at least one radiation detector rotatable with the rotor, and a motivator operatively connected to the rotor. The stator, the rotor, the at least one radiation source, and the at least one radiation detector may be located within a housing. A conveyor system may extend through the housing and the rotor. A shielding system including a series of independently movable energy shields sized, shaped, and positioned to at least partially occlude a pathway along which the conveyor system extends may extend from an entrance to the housing, through the rotor, to an exit from the housing. A control system may be configured to cause the shielding system to automatically and dynamically move individual energy shields in response to advancement of one or more objects supported on the conveyor system.

摘要： Axisymmetric solid of revolution derivable from section at FIG. 5 is generally toroidal with electric current(s) in windings preferably flowing circumferentially along major circle(s) during power coupling device operation. Current(s) in windings, current(s) in half-shields, and the volume of space swept out by shield airgap(s) emerge from plane of paper perpendicularly at FIG. 5, but as these emerge therefrom, they curve to follow toroidal major circle(s). Core regions preferably shunt and align magnetic flux such that magnetic field lines escape therefrom primarily only in region(s) of core airgap(s) and such that magnetic flux loops lie in planes of toroidal minor circle(s). Half-shield(s) preferably have electrically conductive material(s) distributed therein as is sufficient to substantially cancel magnetic flux lines impinging thereon before effects of such impinging magnetic flux lines would reach shield airgap(s) and/or outer surface(s) of half-shields.

摘要： Provided are one or more systems and/or techniques for mitigating motion artifacts in a computed tomography image of an anatomical object. Extended scan data is received and includes projections and backprojections acquired for parallel rays emitted by a radiation source at different angular locations within a first range of source angles. The projections and the backprojections are compared to identify differences between the projections and the backprojections at the different angular locations. Movement of the anatomical object during acquisition of the extended scan data at the different angular locations is quantified, and short scan data is identified. The short set includes a subset of the extended scan data acquired at different locations within a second range of source angles where the quantified movement of the anatomical object is less than a movement threshold. The computed tomography image of the anatomical object is reconstructed from the short scan data.

摘要： A detector array (118) for a radiation system includes first and second detector cells (202, 250). The first detector cell (202) includes a first scintillator (220) that converts a radiation photon (226) impinging the first scintillator (220) into first light energy (230), and a first solar cell (212) that converts the first light energy (230) into first electrical energy. The second detector cell (250) includes a second scintillator (270) that converts a radiation photon (276) impinging the second scintillator (270) into second light energy (280). The first scintillator (220) includes a first detection surface (224) through which the radiation photon (226) impinging the first scintillator (220) enters the first scintillator (220). The second scintillator (270) includes a second detection surface (274) through which the radiation photon (276) impinging the second scintillator (270) enters the second scintillator (270). The second detection surface (274) is substantially parallel to the first detection surface (224) and the second detection surface (274) is not coplanar with the first detection surface (224).

摘要： One or more techniques and/or systems are described for generating power on a rotating unit of a system, such as a radiation system (e.g., CT system). The rotating unit comprises a generator that comprises a drive wheel. The drive wheel interfaces with a drive mechanism of a stationary unit. As the rotating unit is moved relative to the stationary unit, the drive wheel rotates along the drive mechanism causing power to be generated by the generator. The power may be supplied to one or more electronic components of the rotating unit.

摘要： A method comprises receiving an output signal of one of multiple detection channels. The method further includes color separating the output signal and generating a color-separated signal substantially only with the peaks corresponding to the detected signals with the principle emission in the emission spectrum range of the detection channel. The method further includes estimating a time-variant amplitude of the gradually decaying tail and removing the time-variant amplitude from the color-separated signal. The method further includes generating a corrected colored-separated signal with substantially only the peaks corresponding to the fluorescent dyes attached to the fragments in the sample.

摘要： Among other things, one or more techniques and/or systems for calibration of a radiation system to compute a gain correction(s) are provided. A calibration procedure is performed during which a portion of the detector array is shadowed by an object, causing the detector array to be non-uniformly exposed to radiation. A portion of a projection generated from the calibration procedure and indicative of radiation that did not traverse the object is separated from a portion of the projection indicative of radiation that did traverse the object, and a gain correction(s) is computed from the portion of the projection indicative of radiation that did not traverse the object (e.g., and is thus indicative of radiation that merely traversed air).
