ABSTRACT:
The invention relates to an arrangement for examining a body comprising a radiation source for producing a primary beam of small cross-section, means for producing a relative displacement between the body on the one hand and the primary beam on the other hand, a detector device sensing the radiation elastically scattered at small scattering angles and means for determining the scattering angle and or the momentum. In an embodiment, a spatial resolution in the direction of the primary beam can be obtained in that several diaphragm lamellae are arranged between the body and the detector device in such a manner that scattered radiation from different sections of the primary beam each time strikes different strips on the surface of the detector device and in that the detector has a lateral resolution in the longitudinal direction of the strips. In another embodiment, a gamma camera is employed as the detector device.
