Running head: COMPARISON OF AMORPHOUS SELENIUM AND AMORPHOUS 1 Comparison of Amorphous Selenium and Amorphous Silicon Flat-Panel Detectors

Digital radiographic flat-panel detectors may operate with direct or indirect manners of converting x-ray photon energy into spatial energy signals. Advances in both technologies have led to radiographic work areas that are faster and lend toward lower patient radiation doses. Superior image quality with an abundance of post-processing capabilities is a benefit as well. Whether based on amorphous selenium or amorphous silicon, detector hardware including the energy absorbing semiconductor components are remarkably small and highly engineered. There are clear benefits of using one detector type over the other and there are areas where comparative research needs to be further examined. At this time, it appears optimal selection of either type depends on selecting the proper detector for the intended application. COMPARISON OF FLAT-PANEL DETECTORS 3
