[Flat Panel Detector Philips introduced and its system direction].
We introduced digital X-ray diagnostic systems with Flat panel detector both in general X-ray systems and in Angiography systems. Our introduced Flat Panel Detector has the latest technology and has Cesium Iodide (CsI) that absorbs X-ray energy and generates visible light. Detected light signals make digital X-ray images. CsI is the most important material because its absorption rate of X-ray influences the strength of output digital signal. The purpose in this paper is checking that is latest Flat Panel Detector pulls out enough capability CsI has. Especially the thickness of CsI relates to X-ray absorption. X-ray absorption rate depended on the thickness of CsI was calculated by using simulated X-ray model and the future direction of Flat Panel Detector system was discussed.
