Task-Specific Optimization of Mammographic Systems

Abstract

During this past year, our research has focused on three objectives. The first objective was to develop a model of scattered radiation in mammographic imaging. This was done to understand how scatter affects image quality by degrading resolution and noise. The second aim continued research that used observer models to understand how resolution and noise affect breast lesion detection and discrimination. The third objective was to conduct an observer experiment with several mammographers to examine how reduced dose and different medical displays affect lesion detection and discrimination. For future work, we will analyze the data from these experiments to understand how resolution and noise separately and jointly affect cancer detection.
