Currently, the glandular dose is evaluated quantitatively on the basis of the measured data using phantom, and not in a dose based on the mammary gland structure of an individual patient. However, mammary gland structures of the patients are different from each other and mammary gland dose of an individual patient cannot be obtained by the existing methods. In this study, we present an automated estimation method of mammary gland dose by means of mammary structure which is measured automatically using mammogram. In this method, mammary gland structure is extracted by Gabor filter; mammary region is segmented by the automated thresholding. For the evaluation, mammograms of 100 patients diagnosed with category 1 were collected. Using these mammograms we compared the mammary gland ratio measured by proposed method and visual evaluation. As a result, 78% of the total cases were matched. Furthermore, the mammary gland ratio and average glandular dose among the patients with same breast thickness was matched well. These results show that the proposed method may be useful for the estimation of average glandular dose for the individual patients.
