Abstract
THE OBJECTIVE OF THE PHASE I EFFORT OF THIS PROJECT IS THE EVALUATION OF AN ADVANCED DIGITAL ELECTRONIC CAMERA FOR MAMMOGRAPHIC SCREENING. THE CAMERA CONSISTS OF A COOLED, SLOW-SCAN CCD-BASED ELECTRONIC STILL CAMERA CAPABLE OF EXTREMELY LOW READOUT NOISE, AND HIGH CONTRAST AND SPATIAL RESOLUTION. THE CCD WILL BE COUPLED TO AN X-RAY SCINTILLATOR WITH A DEMAGNIFYING COLLIMATED FIBER OPTIC. PRELIMINARY INVESTIGATIONS OF A SYSTEM SIMILAR TO THE ONE TO BE USED IN THIS STUDY INDICATE THAT THE APPROACH SHOULD GIVE RESULTS THAT ARE X-RAY PHOTON SHOT NOISE LIMITED. THE PHASE I EFFORT WILL BE LIMITED TO PHYSICAL EXPERIMENTS TO DETERMINE SIGNAL-TO-NOISE RATIO AND CONTRAST RATIO CAPABILITIES IN COMPARISON WITH THE FILM/SCREEN COMBINATIONS CURRENTLY IN USE.
