撮影装置。 An image detection system consisting of a combination of an X-ray tube, a detector that is supported opposite to the X-ray tube with a subject in between and converts transmitted X-rays into visible light, and a television camera that photographs the output optical image. Both of the above scan and move in a trajectory other than a straight line while maintaining a symmetrical position around a predetermined region within the subject, and each generates two-dimensional projections of the subject in multiple directions and positions on this scanning trajectory. In a digital tomography device that measures images, digitizes these two-dimensional projected images, and performs calculation processing to create a tomographic image of the subject,
A digital tomography apparatus characterized in that the moving mechanism of the image detection system always makes the moving direction of its scanning trajectory coincide with the scanning direction of the television camera.
