SYSTEMS AND METHODS FOR X-RAY COMPUTED TOMOGRAPHY

A system and method for X-ray computed tomography includes a robotic arm that moves an X-ray emitter around a subject in a curvilinear path and an X-ray detector that captures 2-dimensional views while the subject is scanned. Movements of the emitter and detector are coordinated such that the position and angle of the emitter relative to the detector remains substantially constant during scanning. A processor uses computed tomography to reconstruct an image of the subject from the captured 2-dimensional views. The robotic arm varies the pitch of the X-ray emitter during the scan to enhance the spatial resolution of the reconstructed image. The processor generates a projection transformation matrix based on movement of the robotic arm for each captured 2-dimensional view that is applied during reconstruction.

STATIONARY X-RAY SOURCE
20210338181 · 2021-11-04 ·

Embodiments provide a stationary X-ray source for a multisource X-ray imaging system for tomographic imaging. The stationary X-ray source includes an array of thermionic cathodes and, in most embodiments a rotating anode. The anode rotates about a rotation axis, however the anode is stationary in the horizontal or vertical dimensions (e.g. about axes perpendicular to the rotation axis). The elimination of mechanical motion improves the image quality by elimination of mechanical vibration and source motion; simplifies system design that reduces system size and cost; increases angular coverage with no increase in scan time; and results in short scan times to, in medical some medical imaging applications, reduce patient-motion-induced blurring.

A diffraction analysis device and a method for a full-field X-ray fluorescence imaging analysis are disclosed. The device includes a switching assembly, collimation assemblies, an X-ray source, an X-ray detector, a laser indicator, and a computer control system. The switching assembly combines with the collimation assemblies to achieve a functional effect that is previously achieved by two different types of devices through only one device by changing the positioning layout of the X-ray source and the X-ray detector. The full-field X-ray fluorescence imaging analysis can be realized, and the crystal phase composition information and the element distribution imaging information of the sample can be quickly obtained through the same device without scanning, which not only greatly improves the utilization rate of each assembly in the device, reduces the assemblies cost of the device, makes the device structure more compact, but also greatly improves the analysis efficiency and detection accuracy.
