An x-ray source for computer tomography uses several sub-sources. An electron beam impacts the several sub-sources to achieve a high x-ray flux with high resolution. The several sub-sources produce a composite image, which is deconvolved to disentangle the composite image and render a useful ...
X-ray, or X-radiation, is a form of electromagnetic radiation that can pass through many materials that are opaque to light. They can be used to take images of the inside of the human body.
The simulation is based on ray-tracing and on the X-ray attenuation law. The use of Computer Aided Drawing (CAD) models enables simulations to be carried out with complex three-dimensional (3D) objects. 模拟的数据基于cad模型,模拟xray光线追踪(实际上这篇文章只用到了光线投射,不考虑其他反射之类的...

X-Ray imaging is a technique that relies on the differential absorption of photons by tissues based on their electron density. It produces two-dimensional images of three-dimensional structures by detecting the photons passing through the body using film or digital detectors. ...

X-ray imaging is the oldest medical imaging modality, which found its way into medical practice shortly after the discovery of the X-rays in 1895. X-ray imaging is a projection technique, and image formation takes place traditionally on photosensitive film, although direct digital X-ray imaging...
