In general, dose evaluation for mammography uses average glandular dose (AGD). AGD and entrance surface dose (ESD) were estimated using PMMA phantom every 10mm from 10 to 60 mm in clinical practice. A mammography examination involves twice of exposure to obtain craniocaudal and mediolateral oblique views. The result of study indicates that a total ESD of a mammographic examination is equally high to breast surface dose of CT, the dose for mammography should be evaluated both AGD and ESD.

This calculator calculates the average glandular dose using conversion factor, averaged exposure measurement values.
