Method for obtaining Enhanced images in x-ray Beam, Beam apparatus for use in x-ray Plane detector to detect gaseous Avalanche and incident Radiation

摘要

A method and apparatus for x-ray Radiography, and especially for Flat Beam and a detector for Detecting Radiation incident.In the method and apparatus, (9) where x-rays are emitted from an x-ray Source (60),To room x shaped Flat Beam and are transmitted through an object to be x-rayed (62)And the x-rays transmitted through the object (62) are detected in a detector (64).The detector (64), the cualdetecta incident Radiation, is a parallel Plate Avalanche Chamber gas,Including Assemblies of electrode between which a Voltage is applied for creating an electrical fieldWhich cause Avalanches of electrons released by Primary and Secondary Ionization laradiacio n incident.The detector (64) is oriented in relation to the incident Radiation (9), so that the Radiation enters Sideways between a First and a Second Parallel Plate,Among which the electrical field is created.The senaleselu00e9ctricas Indu down by these electron ion Avalanches are detected by at least one mounting deelectrodo detectorIncluding a Plurality of electrode detector Elements arranged adjacent to each other, each along unadireccion ncialmente than that parallel to the incident Radiation.The pulses from each detector electrode Element are processed in processing Electronics,For pixel values corresponding to the respective Element deelectrodo detector
