Workstation interface for ROC studies in digital mammography

The goal of this project was the development of a workstation-user interface for evaluating computer assisted diagnosis (CAD) methods for digital mammography in receiver operating characteristic (ROC) experiments. Digital mammography poses significant and unique difficulties in the design and implementation of such an interface because multiple, large size images need to be handled at high- speeds. Furthermore, controls such as contrast, pan and zoom, and tools such as reporting forms, case information, and analysis of results need to be included. The software and hardware used to develop such a workstation and interface were based on Sun platforms and the Unix operating system. The software was evaluated by radiologists, and found to be user friendly, and comparable to standard mammography film reading in terms of display layout and speed. The software, as designed, will work on entry level workstations as well as high-end workstations with specialized hardware, thus being usable in either an educational, training, or clinical environment for annotation purposes using CAD techniques as well as primary diagnosis.
