Method and a device for radiography and a radiation detector

摘要: A method and apparatus for radiography, a detector detecting incident radiation. In the apparatus, wherein X-rays ( 9 ) are emitted from an X-ray source 60 ), formed into planar beam transmitted through object to be imaged 62 said detected in chamber( 64 ). The chamber which detects radiation, including electrode arrangements between voltage is applied creating electrical field, may cause electron-ion avalanches of primary secondary ionisation electrons released by oriented, relation radiation so that preferably enters sideways first second essentially parallel plate, field created. Electrical signals induced at least one arrangement, plurality elements arranged adjacent each other, along direction being Pulses element processed processing electronics, obtaining values pixel corresponding respective element. atoms with photons interacting belong liquid, temperature −30° C. room temperature, or solid material.
