Determination of equivalent breast phantoms for different age groups of Taiwanese women: an experimental approach.

Purpose: Polymethylmethacrylate (PMMA) slab is one of the mostly used phantoms for studying breast dosimetry in mammography. The purpose of this study was to evaluate the equivalence between exposure factors acquired from PMMA slabs and patient cases of different age groups of Taiwanese women in mammography.

Methods: This study included 3910 craniocaudal screen/film mammograms on Taiwanese women acquired on one mammographic unit.

Development of an adjustable model breast for mammographic dosimetry assessment in Taiwanese women.

Objective: The currently used model breast for mammographic dosimetry assessment lacks the flexibility to change dimensions. The aim of this study was to develop an adjustable model breast for mammographic dosimetry assessment of Taiwanese women.

Materials And Methods: A retrospective review of 4226 craniocaudal (CC) views was conducted.
