Measurement of Half-value Layer in Mammography
Japanese Journal of Radiological Technology, 2003 The half-value layer (HVL) of an X-ray beam for film-screen mammography is considered an important parameter for image quality and patient dose. Thus, HVL must be measured in accordance with The Manual of Accuracy for Mammography printed by the Japanese Society of Radiological Technology.

The Precision of Half-value Layer Measurement on Mammography
Japanese Journal of Radiological Technology, 2011 The half-value layer (HVL) is an important index of the image quality or radiation risk in mammography. Radiation risk of the breast tissue is evaluated with the average glandular dose. The HVL index is indispensable for the average glandular dose computations.
