摘要： A tomographic x-ray machine has camera and film-plane sections which move about a primary axis for imaging a selected cross-section of an anatomical member onto a film. A "scout image" of the member is obtained at right angles to the plane of the desired cross-section to indicate the cross-section's orientation with respect to the primary axis. The anatomical member is then moved to place it on the primary axis and a second film is located at the same angle that the selected cross-section makes with the primary axis. The second film and the cross-section are then maintained in parallel planes throughout motion of the camera and the second film during tomographic radiography.
