摘要： 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.

摘要： 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. The invention is applicable with energy discriminating CT systems as well as with conventional CT systems and other multi-energy CT systems, such as dual kVp-based systems.

摘要： 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.

摘要： 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.

摘要翻译： 提出了一种自适应CT数据采集系统和技术，其中动态地控制用于CT数据采集的辐射，以限制在给定数据采集期间可能特别容易饱和的CT检测器组件的那些检测器的暴露。 数据采集技术认识到，对于给定的主体大小和位置，预辐射滤波和辐射束的准直可能不足以完全防止检测器饱和。 因此，本发明包括实现用于校正饱和CT检测器的其他不可用数据的多个CT数据校正技术。 这些数据校正技术包括最近邻校正，偏心幻像校正，偏心合成数据校正，侦察数据校正，平面放射线图校正以及其他数目。 本发明适用于能量识别CT系统以及常规CT系统和其他多能CT系统，例如基于双kVp的系统。
