A tomographic system in which electronic movement of the x-ray source and the image receptor replace the mechanical movement of conventional tomography has been constructed and tested. Because the system permits very short, rapidly repeated exposures, viewing by television provides real-time fluoroscopic tomography, termed tomoscopy. Further, electronic adjustment of tomographic layer height permits rapid direct search for the optimum layer. The system requires no more than conventional fluoroscopic radiation levels and resolves 3 line pairs per millimeter (LP/mm) in the televised image and 4 LP/mm in the spot film images. It offers rapid, highly customized, high-resolution tomography under direct fluoroscopic control. Precise percutaneous biopsy with integrated needle-controlled equipment and tomography of contrast-filled blood vessels incorporating digital subtraction principles are theoretic possibilities.
一种断层扫描系统已经构建并测试完毕，该系统中X射线源和图像接收器的电子移动取代了传统断层扫描的机械移动。由于该系统允许进行非常短的、快速重复的曝光，通过电视观看可提供实时荧光透视断层扫描，称为断层透视。此外，断层扫描层高度的电子调节允许快速直接搜索最佳层。该系统所需的辐射水平不超过传统荧光透视的辐射水平，在电视图像中分辨率为每毫米3线对（LP/mm），在点片图像中为4 LP/mm。它可在直接荧光透视控制下提供快速、高度定制的高分辨率断层扫描。使用集成针控设备进行精确的经皮活检以及结合数字减法原理对造影剂充盈的血管进行断层扫描在理论上是可行的。
