Clinical and Technical Performance Evaluation of a Digital Mammography System

Abstract

The goal of the research effort funded under this grant is to finalize the construction of two prototype DXM-1 slot-scanning digital mammography systems, conduct a technical evaluation of these prototypes and perform a clinical study to assess the efficacy of the system in the clinical environment. The technical evaluation conducted at the Radiology Department at the University of Arizona (UA). The objective of the technical evaluation is to determine system performance parameters such as dynamic range, modulation transfer function, sensitivity, etc. The clinical study is scheduled to be conducted at the Radiology Department at the University of California at San Diego (UCSD) and will establish the clinical efficacy of the system compared with conventional film/screen mammography. Construction of the prototypes is complete and the technical evaluation has been completed. Clinical images have been obtained with 2 patients. Preliminary data gathered indicates that image quality parameters of the DXM-1 system are superior to film/screen mammography and can be obtained with lower patient dose.
