摘要： Disclosed embodiments include an x-ray imaging system and method that includes a radiation source configured to generate radiation directed toward an object. A computing device may be configured to monitor a number of pixels and capture imaging data when at least some of the radiation passes through the object and impinges on the number of detectors enabling adaptive frame grabbing, which may optionally provide image data input for automatic exposure control (AEC) for exposure duration adjustment based on an AEC output. Such systems and methods may significantly simplify system implementation, irrespective of angular range, number of projection views and scan time in tomosynthesis and other three-dimensional x-ray systems, as well as for two-dimensional x-ray scans with variable exposure pulse duration.
