Abstract

This study evaluated how tube potential-filter combinations [with a molybdenum (Mo) anode and either an Mo or a rhodium (Rh) filter] influence image quality and radiation dose to breasts of different thicknesses in film-screen mammography using a new mammography phantom (CDMAM Phantom Type 3.4). A 28-kVp/Mo tube potential-filter combination is recommended for a breast (phantom) thickness of 40 mm or less, 28 kVp/Rh for a breast (phantom) thickness of 60 mm or less, and 30 kVp/Rh for a breast (phantom) thickness greater than 60 mm.

摘要

本研究使用一种新型乳腺摄影体模（CDMAM 3.4型体模），评估了在乳腺X线胶片摄影中，管电压-滤过组合[钼（Mo）靶且搭配Mo或铑（Rh）滤过]如何影响不同厚度乳房的图像质量和辐射剂量。对于乳房（体模）厚度为40mm及以下的情况，推荐使用28 kVp/Mo管电压-滤过组合；对于乳房（体模）厚度为60mm及以下的情况，推荐使用28 kVp/Rh；对于乳房（体模）厚度大于60mm的情况，推荐使用30 kVp/Rh。
