Area of Science:

  • Medical Imaging
  • Radiology Informatics
  • Human-Computer Interaction

Background:

  • Digital mammography offers softcopy display advantages over traditional film.
  • Softcopy mammogram display presents challenges due to high spatial and contrast resolution demands.

Purpose of the Study:

  • To describe the design and development of the Mammoview softcopy display application.
  • To evaluate the performance of Mammoview for mammogram interpretation.
  • To identify requirements for successful softcopy display stations.

Main Methods:

  • Development of the Mammoview softcopy display application.
  • Conducting clinical studies to measure radiologist speed and accuracy.
  • Analyzing user interactions and feedback from demonstrations and trials.

Main Results:

  • Radiologist performance with Mammoview was comparable to film alternators in speed and accuracy.
  • Simpler interfaces, reader variability, and larger image-to-display size ratios influenced review times.
  • Radiologists reported good acceptance and comfort with the Mammoview interface for clinical use.

Conclusions:

  • Softcopy mammography display stations can achieve performance levels similar to film-based systems.
  • Interface design, user factors, and image scaling are critical for optimizing softcopy mammography efficiency.
  • Integration of computer-aided detection (CAD) shows potential for improving accuracy without increasing reading time.
