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. Better than 0.2 mm overall spatial precision can be achieved with the digital tomosynthesis imaging.

摘要： An X-ray imaging system using multiple pulsed X-ray sources in motion to perform high 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. Each individual X-ray source can also move rapidly around its static position in a small distance. When an X-ray source 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 stay momentarily standstill. It results in much reduced source travel distance for each X-ray source. 3D scan can cover much wider sweep angle in much shorter time and image analysis can also be done in real-time.

摘要： An X-ray line-scan camera utilizes an image transferring means to alter the optical path and thus eliminates the X-ray radiation damage on the electrical components of the camera system. The camera comprises a layer of scintillating material, a fiber optic face plate (FOFP) block, and an array of image sensors. One face of the FOFP block is bonded to the surface of the image sensors. The layer of scintillating material is placed on other face of the FOFP block and used to convert an impinging X-ray beam into visible light. The FOFP block is used to transfer the visible light from the scintillating layer onto the image sensor array, which in turn converts the visible light into electrical video signals. The FOFP block has a rotation angle of 32 to 40 degree relative to the impinging X-ray beam to prevent direct impingement of the X-ray beam onto the image sensors.

摘要： A radiation damage resistant linear X-ray detector system based on a unique image transferring principle to alter the optical path and thus reduces or eliminates the X-ray radiation damage on the electrical components of the detector system. The system includes a layer of scintillating material, a fiber optic face plate (FOFP), and an array of image sensors. One face of the FOFP is bonded to the surface of the image sensors. The layer of scintillating material, such as Gd2O2S:Tb (GOS or GADOX), CsI(TI), or CdWO4, is placed on other face of the FOFP and used to convert the impinging X-ray energies into visible light which can be detected efficiently by the image sensor array. The FOFP is used to transfer the visible light from the scintillating layer onto the image sensor array after the X-ray flux has been converted. The photon energy of the visible light is collected with a scanning image sensor array that converts the photon energy proportionally into electrical video signals and enables the signals to be processed using standard image processing software and equipment.

摘要： 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.

摘要： A system and method for improved image acquisition of multiple pulsed X-ray source-in-motion tomosynthesis imaging apparatus by generating the electrocardiogram (ECG) waveform data using an ECG device. Once a representative cardiac cycle is determined, system will acquire images only at rest period of heart beat. Real time ECG waveform is used as ECG synchronization for image improvement. The imaging apparatus avoids ECG peak pulse for better chest, lung and breast imaging under influence of cardiac periodical motion. As a result, smoother data acquisition, much higher data quality can be achieved. The multiple pulsed X-ray source-in-motion tomosynthesis machine is with distributed multiple X-ray sources that is spanned at wide scan angle. At rest period of one heartbeat, multiple X-ray exposures are acquired from X-ray sources at different angles. The machine itself has capability to acquire as many as 60 actual projection images within about two seconds.

摘要： 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.
