More Book Details

Description of the Book:

The goal of this project is to develop a computer-aided diagnosis (CAD) system for mass detection using advanced computer vision techniques that will be trained with retrospectively detected cancers on prior mammograms. The new CAD system will be combined with our existing CAD system. When fully developed, the new dual CAD system should increase the sensitivity of detecting cancers at the early stage without compromising the sensitivity for other cancers. During this project year, we have performed the following tasks: (1) continue to collect the data sets of digitized film mammograms for testing our CAD system, (2) investigation of a bilateral approach to reduce the false positives (FPs) on single CAD system, (3) develop image processing techniques for improvement of mass detection on prior mammograms, and (4) continue to develop a two-view information fusion method to improve the performance of single CAD system. In summary, we have investigated a number of areas in CAD of mammographic masses and evaluated the new techniques for mass detection on mammograms.

We have made progress in three of the tasks proposed in the project. We have found that our new computer-vision techniques can improve the performance of the CAD systems. We will continue the development of the CAD system in the coming years
