Dual-energy system for quantitative radiographic imaging

摘要: A dual photon bone densitometry apparatus uses an area scanning technique to minimize time. X-rays are generated by x-ray source which pass through a region of subject's body, forming image reaches scintillation screen. The screen reradiates spatial intensity pattern corresponding the image, being detected CCD sensor. is digitized sensor and processed controller before stored as electronic image. energy that delivers two different levels provides quantitative information regarding object imaged using standard absorptiometry techniques.
