Abstract: The invention is directed to an x-ray flux management device that adaptively attenuates an x-ray beam to limit the incident flux reaching a subject and radiographic detectors in potentially high-flux areas while not affecting the incident flux and detector measurements in low-flux regions. While the invention is particularly well-suited for CT, the invention is also applicable with other x-ray imaging systems. In addition to reducing the required detector system dynamic range, the present invention provides an added advantage of reducing radiation dose.

Abstract: Methods and systems for controlling an X-ray imaging system. The method for controlling an X-ray imaging system includes acquiring a plurality of subviews of patient attenuation data wherein a first set of subviews of patient attenuation data is acquired at a first radiation flux level and a second set of subviews of patient attenuation data is acquired at a second radiation flux level. The first radiation flux level is different than the second radiation flux level. The method further includes combining the first set of subviews of patient attenuation data and the second set of subviews of patient attenuation data to form corrected views for subsequent image generation.

Abstract: Disclosed herein is a computed tomography (CT) detector module, for coupling with a collimator rail. The CT detector module includes a CT detector pack, a printed circuit board, and electrical conductor, and a substrate. The electrical conductor is disposed between and in electrical communication with the CT detector pack and the printed circuit board. The substrate has a slot and is disposed between the CT detector pack and the circuit board such that the electrical conductor is routed through the slot.

Abstract: The present invention is a directed method and apparatus for collimating a radiation beam such that the full intensity of the radiation beam does not impinge detectors of a radiation detector assembly that are particularly susceptible to saturation or over-ranging. This collimation can be dynamically adjusted on a per view basis using empirical or scout scan data.

Abstract: The present invention is a directed method and apparatus for collimating a radiation beam such that the full intensity of the radiation beam does not impinge detectors of a radiation detector assembly that are particularly susceptible to saturation or over-ranging.

Abstract: An adaptive CT data acquisition system and technique is presented whereby radiation emitted for CT data acquisition is dynamically controlled to limit exposure to those detectors of a CT detector assembly that may be particularly susceptible to saturation during a given data acquisition. The data acquisition technique recognizes that for a given subject size and position that pre-subject filtering and collimating of a radiation beam may be insufficient to completely prevent detector saturation. Therefore, the present invention includes implementation of a number of CT data correction techniques for correcting otherwise unusable data of a saturated CT detector. These data correction techniques include a nearest neighbor correction, off-centered phantom correction, off-centered synthetic data correction, scout data correction, planar radiogram correction, and a number of others.
