摘要
The aim of this study was to evaluate the physical performance of an experimental flat-panel digital X-ray detector plate (FDXD), and to assess clinical potential in radiographic and fluoroscopic node. The efficiency of the detector was assessed by the low-frequency detective quantum efficiency and a measure of image quality was threshold contrast detail detectability object. A range of clinical examinations out and the results reviewed members of the radiology staff. The DQE(0) of system was calculated to be almost 75%, compared with a value of approximately 20% for modern computed radiography equipment, offering the potential image quality or significant dose Measurements using the TCDD test object demonstrated a corresponding advantage for the image quality and dose efficiency. Clinical are producing radiographic results which are the equal of the best currently available digital and a limited number of examinations fluoroscopic mode at 25 frames per second have equally encouraging. Equipment using FDXD technology could potentially fulfill all the radiographic and fluoroscopic requirements of the digital department improved image quality image quality and dose efficiency.
