Paper Abstract

The design of a proposed CCD mosaic concept for digital mammography uses a lead shied with through holes to reduce the patient exposure in regions of the mosaic where there are no CCDs. This shield also has an inherent advantage of reducing the amount of scattered x-rays. We examined the scatter-to-primary ratio dependency with aperture size above and below the breast and air gap distance between the CCD assembly and the bottom of the breast. These results are discussed in regards to the optimization of the CCD mosaic concept and theoretical calculations.
