SLIT RADIATION CAMERA HAVING INDIVIDUALLY CONTROLLABLE ATTENUATING ELEMENT COOPERATED WITH SLIT THROTTLE

An apparatus for slit radiography comprising an X-ray source by means of which a body being irradiated can be scanned through a slit diaphragm by a substantially planar, fan-shaped X-ray beam, the scanning X-ray beam passed through the body impinging upon an X-ray detector. The apparatus comprises c...

Beschreibung
Zusammenfassung:	An apparatus for slit radiography comprising an X-ray source by means of which a body being irradiated can be scanned through a slit diaphragm by a substantially planar, fan-shaped X-ray beam, the scanning X-ray beam passed through the body impinging upon an X-ray detector. The apparatus comprises controllable attenuation elements coacting with the slit diaphragm, each element being adapted to influence a sector of the scanning X-ray beam under the control of signals generated by a radiation detector device. The radiation detector device is disposed between the body being irradiated and the X-ray detector. The radiation detector device comprises at least one radiation detector extending at any moment into the scanning X-ray beam passed through the body and moving in synchronism with the scanning movement of the X-ray beam. The radiation detector device is divided into sections corresponding with the sectors of the scanning X-ray beam influenceable by the attenuation elements, while, in operation, each section of the radiation detector device generates a signal usable for controlling the attenuation elements.
