X-ray quanta measuring device including diaphragm for producing conical radiation beam on object being measured
First Claim
1. A device for measuring the pulse transfer spectrum of X-ray quanta which are elastically scattered in an examination zone of an X-ray system comprising a polychromatic x-ray source on one side of the examination zone, said measuring device comprising:
- a detector on the other side of the zone for measuring the energy of the X-ray quanta; and
two apertured diaphragms which have a common symmetry axis and which transmit scattered radiation to the detector only within a given scattering angle range, a first diaphragm being between the examination zone and the X-ray source and a second diaphragm between the examination zone and the detector, the first diaphragm being constructed so that the X-rays transmitted therethrough form a conical envelope of a primary radiation cone, the second diaphragm being constructed so that scattered radiation produced in the examination zone is incident on the detector in an annular symmetrical fashion with respect to said axis of symmetry.

Abstract
A device for measuring the pulse transfer of X-ray quanta which are elastically scattered in an examination zone, includes an X-ray source which is arranged on one side of the examination zone, a detector which is situated on the other side of the examination zone and which measures the energy of the X-ray quanta, and a rotationally-symmetrical diaphragm device which is arranged between the detector and the X-ray source. In a device of this kind a comparatively accurate determination of the pulse transfer is also possible for thick objects, because the diaphragm device is constructed so that the X-ray quanta emitted by the X-ray beam source are transmitted to the examination zone only on the envelope of a cone.
