抄録

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 manual prescribes exactly the geometry of measurement, chamber position of measurement in the field, selection of chamber, and so on. However, the measurement of HVL is difficult in the actual clinical setting. This study examined the results of failure to perform the measurement of HVL in accordance with the manual for measuring HVL in the clinical setting. The investigation indicated that serious problems do not arise when measuring HVL for routine quality control even if the chamber in the field is not always set according to the manual and if a chamber for radiotherapy or diagnosis is used that is not recommended for soft X-ray by the manual.
