Abstract Background Reliable estimates of radiation dose to bone marrow are critical to understanding the risk of radiation‐induced cancers. Although the medical internal radiation dose phantom is routinely used for dose estimation, bone marrow is

Purpose The study illustrates how a renewed approach to medical physics, Medical Physics 3.0 (MP3.0), can identify performance decrement of digital radiography (DR) systems when conventional Medical Physics 1.0 (MP1.0) methods fail. Methods MP1.0 tes

Beginning with the advent of digital radiography systems in 1981, manufacturers of these systems provided indicators of detector exposure. These indicators were manufacturer-specific, and users in facilities with equipment from multiple manufacturers

Genome Announcements
We describe three newly isolated phages—Obliviate, UmaThurman, and Guacamole—that infect Gordonia terrae 3612. The three genomes are related to one another but are not closely related to other previously sequenced phages or prophages. The three p

Purpose: The conditions under which vendor performance criteria for digital radiography systems are obtained do not adequately simulate the conditions of actual clinical imaging with respect to radiographic technique factors, scatter production, and
