Can the a-Si flat panel detector be provided with different types of fluoroscopic screens and what is the effect?
Yes, any a-Si flat panel detector can be offered with one of two types of fluoroscopic screens, either a Fine screen or a Fast screen. The Fine screen type stresses the fine sharp images with up to 4 line/per mm and is best for use with easier to penetrate items. The Fast screen type is a more sensitive screen that provides approx. 6-7 times more light at the price of gaining some unsharpness, albeit small. This screen would be the choice for difficult to penetrate items like thick concrete, steel, etc. and is used in most applications.
