摘要：

We devised the method of evaluating breast composition from clinical mammograms by using digital image processing techniques and the simulating breast tissue phantom. The computer-assisted system was built, which contributed to evaluating average radiation absorbed dose to glandular breast tissue (average glandular dose). This system consists of three sections and requires a look-up table to be prepared for each section, The three look-up tables concern average glandular dose per unit entrance skin exposure, skin exposure in air and breast composition vs. pixel value. This system was actually applied to the clinical mammograms of about 50 examples, and the results were analyzed.
