PORTABLE DIGITAL IMAGING DETECTOR SYSTEM

BIR PROPOSES AN INNOVATIVE PORTABLE X-RAY DETECTION AND MEASUREMENT SYSTEM FOR NDE APPLICATIONS. BASED ON A FILMLESS CASSETTE OF DISCRETE DIGITAL X-RAY DECECTORS, SUCH A SYSTEM WOULD ENABLE DIRECT DIGITAL IMAGING FOR VIEWING, VCR RECORDING, OR FOR COMPUTER ANALYSIS. THE SYSTEM WOULD RESEMBLE A FILM CASSETTE IN ITS PORTABILITY AND IMAGE SENSITIVITY AND RESOLUTION. WE PROPOSE TO CAREFULLY EVALUATE THE X-RAY INSPECTION APPLICATIONS WHICH NASA CURRENTLY HAS FOR A PORTABLE DIGITALDETECTOR SYSTEM. THE RESULTING INFORMATION WILL BE USED TO GENERATE AN OPTIMAL DETECTOR SPECIFICATION. THIS DETECTOR DESIGN WILL BE EVALUATED WITH SEVERAL X-RAY SOURCES TO QUANTIFY ITS PERFORMANCE CAPABILITIES. SAMPLE IMAGES OF SELECTED NASA PARTS WILL BE ACQUIRED AND PROCESSED FOR INCLUSION IN THE FINAL REPORT. PENDING FAVORABLE EXPERIMENTAL RESULTS, THE GENERAL SYSTEM CONFIGURATION AND THE SPECIFIC DESIGN PARAMETERS NEEDED TO SUIT NASA'S NEEDS WILL BE DEFINED AT THE END OF PHASE I, LEADING TO THE FABRICATION OF A PROTOTYPE IN PHASE II.
