摘要:
A system for spectroscopic imaging of bodily tissue in which a scintillation screen (20) and a charged coupled device (24) (CCD) are used to accurately image selected tissue. An x-ray source (12) generates X-rays which pass through a region of a subject's body, forming an X-ray image which reaches the scintillation screen (20). The scintillation screen (20) reradiates a spatial intensity pattern corresponding to the image, the pattern being detected by a CCD sensor (24). The image is digitized by the sensor (24) and processed by a controller (30) before being stored as an electronic image. Each image is directed onto an associated respective CCD or amorphous silicon detector to generate individual electronic representations of the separate images.
