Abstract: System and method are disclosed for imaging acquisition from sparse partial scans of distributed wide angle. During real time image reconstruction, artificial intelligence (AI) determines if there is enough information to perform diagnostics based on initial scans. If there is enough information from the fractional scans, then data acquisition stops; if more information is needed, then system performs another round of wide-angle sparse scans in a new location progressively until a result is satisfactory. The system reduces X-ray dose on a patient and performs quicker X-ray scan at multiple pulsed source-in-motion tomosynthesis imaging system. The method and system also significantly reduce the amount of time required to display high quality three-dimensional tomosynthesis images.

Abstract: An X-ray imaging system using multiple pulsed X-ray sources to perform highly efficient and ultrafast 3D radiography is presented. There are multiple pulsed X-ray sources mounted on a structure in motion to form an array of sources. The multiple X-ray sources move simultaneously relative to an object on a pre-defined arc track at a constant speed as a group. Electron beam inside each individual X-ray tube is deflected by magnetic or electrical field to move focal spot a small distance. When focal spot of an X-ray tube beam has a speed that is equal to group speed but with opposite moving direction, the X-ray source and X-ray flat panel detector are activated through an external exposure control unit so that source tube stay momentarily standstill equivalently. 3D scan can cover much wider sweep angle in much shorter time and image analysis can also be done in real-time.

Abstract: A modular X-ray source and method for replacement of such an X-ray source are disclosed. The source is inside a consumable modular enclosure where the entire assembly is swapped out during maintenance. The enclosure covers an X-ray tube, high voltage circuit boards 6 and cooling insulating oil are arranged inside the module enclosure. The enclosure structure includes an X-ray window, connector engagement alignment guide and electrical connectors. The modular X-ray source is used in a multiple source tomosynthesis imaging system where multiple pulsed X-ray sources are utilized. The easy replacement of X-ray tube assembly inside the consumable modular enclosure results in lower maintenance cost and overall reliable X-ray imaging machine. The modular source has potential to increase the machine volume in the field and create new standards for replaceable modular X-ray source.
