Abstract: Soft x-ray radiation, which has a lower level of radiation, is transmitted to a target (i.e., the breast). The transmitted image of the target is refined through various computerized processes. All data is stored in a multiple image memory or filed in a laser having a large memory capacity. Stored images can be viewed on a a TV monitor or recalled and interfaced to a host computer. Accordingly, the present invention is designed for mass-screening. The whole sequence of data acquisition and processing is controlled by an operation controller, which also controls the accelerating voltage of the soft x-ray radiation. The equipment is not limited for use in detecting breast cancer and is equally adapted in examining infants or others who cannot tolerate large or heavy radiation dosages.
