Proper equipment calibration and maintenance are some of the most critical components of making sure your imaging systems are safe and produce quality images. Medical physicists are extremely important players in this arena, bridging the gap between technologists and physicians to make sure diagnostic imaging equipment is functioning optimally. In this one-hour session, Phillip Patton, PhD, CHP, DABR, DABSNM, reviews basic components of physics testing for ADI systems, highlights key differences in state requirements for physicists and explains why it is important to hire a qualified medical physicist for your physics testing when applying for RadSite Accreditation.
