MULTIMEDIA DETECTORS FOR MEDICAL IMAGING |
摘要 |
The application of gas-detection principles on both dual-energy detection, such as for chest radiography and mammography, and quantitative autoradiography enhances dramatically the image quality of the digital dual-energy detector with great implications in general-purpose digital radiography, computer assisted tomography (CT), microtomography and x-ray microscopy, and offers notable advantages over film autoradiography with a higher sensitivity, much lower exposure times, as well as imaging access at the cellular level. A gas microstrip detector (20) receives incident radiation (44) through a subject (45) to generate an image. The detector (20) includes a substrate (26) having on a first surface a plurality of alternating anodes (22) and cathodes (24), a detector cathode (30) spaced apart from and opposing the substrate, and a zone for dispensing a gaseous medium (34) between the substrate and the detector cathode and for receiving incident radiation imparted through the subject.
