Abstract: A transport system with curved track pair is constructed for multiple pulsed X-ray source-in-motion to perform fast digital tomosynthesis imaging. It includes a curved rigid track pair with predetermined curvature, a primary motor stage car loaded with X-ray sources and wheels loaded with tension or compression springs. The car is driven by primary motor mounted at base frame and an engaged gear mounted at the car. The car can carry heavy loads, travel with high precision and high repeatability at all installation orientations while motion vibration is minimal. It is also scalable to have a larger radius. Track angle span usually can be from about ten degrees to about 170 degrees. During imaging acquisition, X-ray sources can sweep precisely from one location to another. The car has enough clearance to move in its path without rubbing wheels on tracks. Better than 0.2 mm overall spatial precision can be achieved with the digital tomosynthesis imaging.

Abstract: An X-ray imaging system using multiple pulsed X-ray sources in motion to perform high efficient and ultrafast 3D radiography using an X-ray flexible curved panel detector is presented. There are multiple pulsed X-ray sources mounted on a structure in motion to form an array of sources. The sources move simultaneously relative to an object on a predefined arc track at a constant speed as a group. Each individual X-ray source can move around its static position at a small distance. When an individual source has a speed equal to group speed, but with opposite moving direction, the individual source and detector are activated. This allows source to stay relatively standstill during activation. The operation results in reduced source travel distance for each individual source. 3D radiography image data can be acquired with much wider sweep angle in much shorter time, and image analysis can also be done in real-time.

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: Provided is a radiation imaging apparatus capable of performing precise imaging without performing pre-imaging in the absence of a subject. According to the present invention, it is possible to provide a radiation imaging apparatus capable of performing precise imaging without performing pre-imaging in the absence of a subject immediately before. That is, the apparatus of the present invention is provided with a phase grating 5 provided with a subject area and a reference area. Both areas each have a predetermined pattern that absorbs radiation, but the patterns are different from each other. In this area, an image of the phase grating 5 is observed in a moire pattern of a long period. This moire image of a long period changes in the positions due to the minute change in the relative position between the phase grating 5 and the absorption grating 6, so it becomes possible to detect the minute change of the relative position between the radiation source, the phase grating 5, and the absorption grating 6 from the image of the reference area.

Abstract: The present disclosure relates to the field of a cabinet x-ray incorporating an x-ray tube, an x-ray detector, and a near-infrared optical system mounted onto the cabinet or positioned within the cabinet, for the production of organic and non-organic images. The computing device receives video data from the near-infrared optical system and determines, based on the video data an optical image displaying the captured real-time image or display images adjacently i.e. Picture-In-Picture (PIP). In particular, the present disclosure also relates to a system and method with corresponding apparatus for capturing a near-infrared image simultaneously with the x-ray image allowing a cabinet x-ray unit to attain and optimize images utilizing near-infrared (NIR) fluorescence for sentinel lymph node (SLN) mapping in breast cancer patients to improve the Sentinel Lymph Node identification and procedure.
