摘要： 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.

摘要： 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.

摘要： The present invention relates to a system (10) and related method for planning a tomographic image acquisition of an object to be imaged by a tomographic imaging scanner (20).The system comprises an input (12) for receiving a 3D pre-scan image of the object and a camera system (14) for capturing 3D image information of the object. The system comprises a processor (16) for determining corresponding image features in the camera image and the pre-scan image. The processor determines an image transformation that relates the corresponding image features to each other, such that the object as represented by the pre-scan image can be transformed to the orientation, position and/or deformation of the object represented in the camera image. The processor plans the image acquisition, in which the pre-scan image is used to determine parameters including scan range. An output (18) outputs a signal representative of the determined plan.
