| 摘要 |
The invention relates to a device for examining a body by means of gamma rays or X-rays, in which a body to be examined is irradiated by a plurality of primary beams having a comparatively small cross-section. The scattered radiation produced is intercepted by detector devices, at least one of which is associated each time with a respective primary beam, and the detector device and an associated slit which images the primary beam on the detector device is arranged so that the detector device is struck essentially only by scattered radiation from this one primary beam. Preferably, the detectors are arranged between the body to be examined and the radiation source, so that they can intercept only the back-scattered radiation.
