Abstract: An X-ray imaging system and a method thereof are provided. In one or more embodiments, the imaging system includes an X-ray detector having neuromorphic X-ray pixels that can be combined with integrating pixels in a single hybrid detector package. The X-ray detector may generate two types of datasets (e.g., output data streams), one of integrating keyframes, the other an asynchronous event stream of intensity changes. In one or more embodiments, the method may include detecting X-rays from an imageable event using the X-ray detector, generating the two types of datasets based on the detected X-rays, and reconstructing one or more images of the imageable event based on the two types of generated datasets. By utilizing artificial intelligence/machine learning, these datasets may be combined to generate novel x-ray imaging modes that include deblurred high dynamic range real-time frame sequences or a high-speed, high dynamic range frame sequence for subsequent viewing.

Abstract: Methods, systems, and apparatus for performing scanning spectral tomographic reconstruction of an object. The imaging system includes a power source that is configured to provide an alternating high voltage. The imaging system includes an X-ray source. The X-ray source includes an array of X-ray emitters that allow fast switching “ON” and “OFF” using a grid electrode. The source is configured to generate an X-ray beam with an energy spectrum based on the alternating high voltage and uses X-ray filters. The imaging system includes a controller configured to operate synchronously with the alternating high voltage. The controller is also configured to drive an actuator to position the X-ray source with respect to an object and drive the source in a pre-defined trajectory about the object. At each position in the trajectory, the controller is configured to control the exposure timing of the emitters based on a predefined firing pattern.

Abstract: Methods, systems, and apparatus for performing spectral tomographic reconstruction of an object. The imaging system includes a power source that is configured to provide a variable high voltage. The imaging system includes a distributed X-ray source. The distributed X-ray source includes an array of X-ray emitters that allows fast switching “ON” and “OFF” using X-ray emitter grid electrode. The distributed X-ray sources is configured to generate an X-ray beam with an energy spectrum based on the variable high voltage and uses additional X-ray filters. The imaging system includes a controller. The controller is configured to operate synchronously with the change of the variable high voltage. The controller is configured to control a timing of when to engage an X-ray emitter of the array of X-ray emitters of the distributed X-ray source based on a predefined firing pattern.
