Spatial Dose Distribution and Exposure Dose During Mammography

Abstract

This during the breast mammography X-ray test, a glass dosimeter and spatial dose measuring meter was used to measure and evaluate the exposure dose and spatial dose distribution of each organs by exposure dose and scattered ray in order to obtain the optimal image for diagnosis and minimize the exposure dose. The usage dose of tube voltage and tube current amount was larger among the young age group, whereas the transmission dose, the glandular dose, etc. were larger among the old age group (<0.001). The influence of dose inequality phenomenon was confirmed since the exposure dose and spatial scattered dose by the scattered ray has increased as they got closer to the X-ray tube cathode and toward the direction of X-ray irradiation. Such results are expected to be presented as data for anticipating the exposure dose of patients and determining a test method during a breast cancer test in the future and also utilized widely as basic important data for reducing the medical exposure dose.
