An X-ray imaging apparatus using dual-energy X-ray absorptiometry

摘要

The present invention relates to an X- ray imaging apparatus using the dual-energy X- ray absorption analysis, more X- ray beam and low-level, high-level X- ray energy spectrum having a high level having a particularly X- ray having an energy spectrum of the wideband generated from the X- crew passed through a pair of filters coupled in parallel with the low-level energy spectrum scanning the subject to separate each of the beam and, thus, each separated by high contrast is independently detected by the image detector is provided with a pair of low-level and high-level X- ray beam X- ray beam that has passed through the object in parallel is to obtain a good quality of the X- ray image on the X- ray imaging apparatus using the dual-energy X- ray absorption analysis that can improve the discrimination ability of the components of the subject. X- ray imaging apparatus using the dual-energy X- ray absorption spectrometry according to the present invention and X- crew emitting X- ray beam; X- ray beam is emitted from the X- crew doedoe provided in part of light emitted, a first filter for passing only a low level by selectively X- ray beam in X- X- ray beam emitted by the sailor with the low-level energy spectrum and, with the X- X- ray filter that passes only the second filter is a high-level selective X- ray beam with a high level of energy spectrum in the X- ray beam emitted by the crew consisting connected in parallel; Is provided in the rear portion of the X- ray filter, a collimator for determining the shape and the direction of movement of low-level and high-level X- ray beam X- ray beam that has passed through the X- ray filter; Is characterized in that the configuration including; and is provided spaced apart a predetermined distance to the rear of the collimator, the low-level X- pair of image detector lines provided in parallel to each beam and to detect the high-level X- ray beam . ;
