The procedure is performed in two stages. First, during the radiographic exposure, the patient is rotated in relation to the X-ray tube and a recording device, namely a cinefluorographic device or a television chain with a video-recorder. In practice the tube and the recording device will be revolved around the patient. Later on, in the second stage, the cinefluorographic image, or the television image of the rotating patient, is projected onto a photographic film. If this film is adequately rotated, a tomographic picture will be produced. The method can be applied to conventional tomography, zonography, transverse tomography, autotomography and orthopantomography.
该程序分两个阶段进行。首先,在放射照相曝光期间,患者相对于X射线管和记录设备旋转,记录设备即电影荧光摄影设备或带有录像机的电视系统。实际上,管和记录设备将围绕患者旋转。随后,在第二阶段,旋转患者的电影荧光图像或电视图像被投射到摄影胶片上。如果该胶片充分旋转,就会产生断层图像。该方法可应用于传统断层摄影、区域摄影、横向断层摄影、自动断层摄影和曲面断层摄影。
