X-RAY IMAGING APPARATUS USING DUAL-ENERGY X-RAY ABSORPTIOMETRY WHICH CAN IMPROVE THE RECOGNIZABILITY OF COMPOSITIONAL COMPONENT OF A SUBJECT

摘要

PURPOSE: An X-ray imaging apparatus using dual-energy X-ray absorptiometry is provided to minimize the inner diameter curing phenomenon and artifacts.;CONSTITUTION: An X-ray imaging apparatus using dual-energy X-ray absorptiometry comprises a X-ray source(100), an X-ray filter(300), a collimator(200) and a pair of image detectors. The X-ray source emits X-ray. The X-ray filter is included in the part of X-ray from X-ray source. The first filter and the second filter are connected to the X-ray filter. The collimator is behind included of the X-ray filter. The collimator determines the shape of X-ray passing through the X-ray filter.;COPYRIGHT KIPO 2012
