Estimation of compressed breast thickness during mammography
Highnam RP., Brady JM., Shepstone BJ.
To estimate radiation dose during mammorgraphy the best thickness must be know. We present a new method for estimating the thickness of a compressed breast using only the breast image as projected onto a mammogram, calibration data such as the mAs value and image processing techniques. The method proves to be of high accuracy (± 0.2 cm for craniocaudal mammograms) and has the advantage over other methods of allowing retrospective estimation of thickness.
