Method of and device for positioning an X-ray cassette |
摘要 |
A method of, and a device for positioning an X-ray cassette (5 or 10) in relation to a source (1) of X-rays that emits radiation in a specific preferred direction (A). Another beam of radiation is emitted parallel to that direction at a specific distance (d) therefrom. The other beam is intercepted by a positioning device (20) secured to the cassette. The device produces a signal as long as the angle of incidence of the other beam does not exceed a specific threshold angle ( theta ) with respect to the normal to the cassette.
