WebThe 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. WebJan 1, 2014 · Abstract. Photon beams are characterized by their intensity and energy. The attenuation coefficient measures the rate at which the beam is attenuated (loses intensity) at depth. A half-value layer is a thickness of material that decreases intensity to half of its original value. In a polyenergetic photon beam, lower energies are attenuated more ...
