Tens of thousands of mammograms are performed daily in the United States. Accumulated radiation biologic data suggest that approximately 90‐rad is the level of radition to the breast above which the incidence of cancer may be increased. A microdose system of roentgenography is described that provides better images at one‐third to one‐fifth the exposure of the commonly used lowdose system and about one‐eighth to one‐tenth the dose of Xeromammography. This system should allow for repeated x‐ray study in a patient as required, without exceeding the critical level.
