已经开发了三维射线照相成像系统，目前正在进行临床评估。根据与X射线源几何形状匹配的几何形状，减少二十张常规射线照片并将其重新投影到显示体积中。图像在观察屏幕上被整合，并产生与屏幕位置相对应的断层平面。通过简单地调整屏幕，可以观察到与扫描平面平行和倾斜的平面。图像在所有方向上都是连续的，分辨率约为2lp/mm，通常是真实尺寸，尽管放大2或3倍很容易产生。
A three-dimensional radiographic imaging system has been developed, and is presently being clinically evaluated. Twenty conventional radiographs are reduced and reprojected into a display volume according to a geometry which matches the X-ray source geometry. The images are integrated on a viewing screen and produce the tomographic plane corresponding to the screen's position. Planes parallel and tilted with respect to the scanning plane can be observed by simply adjusting the screen. The image is continuous in all directions, possesses a resolution of about 2lp/mm, and is usually true-sized, although factors of 2 or 3 in magnification can be easily produced.
