ABSTRACT DUAL MODALITY CAMERA FOR X-RAY AND FLUORESCENCE IMAGING SYSTEM Low cost X-ray detector is designed using inorganic scintillator cesium iodide doped with thallium(CsI(Tl)). High resolution is achieved using CsI scintillator instead of phosphor screen. Scintillator screen is coupled with a high frame rate CMOS (Complementary Metal Oxide Semiconductor) camera. Overall cost of the camera is less compare to the available flat panel X-ray detector. The CMOS camera also allows high frame rate imaging. Using the same setup, fluorescence imaging can be done by removing the scintillator in the path of X-ray. Filter can be placed instead of the scintillator and the corresponding focus setup can be done in automation. Most Illustrative Figure: FIG.1
