We have identified several opportunities for improving the quality and usefulness of such images by using digital image acquisition and display techniques to overcome the limitations of film imaging. One key application is in mammographic imaging for detection of breast cancer. Several technical factors limit current mammography in detecting subtle signs of early breast cancer. We have shown the potential for digital systems to increase the sensitivity of this technique, while at the same time allowing the radiation doses to be kept as low as possible. Once images are in digital form, they are easily processed, transmitted to other locations for consultation, or manipulated to enhance the visibility of important features.
Images can also be much more efficiently stored and retrieved in digital form.
Analysis of digitized mammograms may also allow the prediction of future risk of breast cancer. Such information could potentially be used to optimize breast-screening programs, ensuring that the women at greatest risk were examined most frequently. Another area of investigation is the use of digital imaging for detection, diagnosis and management of disease in cardiology. I. Phosphor screens.
