Comparação entre métodos de medição da camada semi-redutora em radiologia
Brazilian Journal of Radiation Sciences, 2021 The Half Value Layer (HVL) is a parameter used in Quality Control (QC), to evaluate the X-ray beam quality. The HVL can be measured through the X-ray primary beam attenuation measurement using knew thickness slabs of 99% purity aluminum (M1) or by ...

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.
