Abstract: Given the many advances in imaging science in the last decade, the need has arisen for a review of NCRP No. 147 and the basis for shielding calculations for medical imaging facilities. NCRP No. 147 is the most commonly used tool for determining shielding requirements for medical imaging facilities, however, advances in imaging including digital breast tomosynthesis, photon counting CT, and widespread use of digital detectors create a need to re-evaluate this document. Changes in workloads, technique factors, use factors, and function all impact shielding design. Leveraging the power of the digital age with systems like EPIC, we can more easily collect accurate data such as workload values. The utility of NCRP No. 147 has been proven time and again, but new technology dictates a need for a revision of this report.

Biosketch: Lisa Genovese is a Diagnostic Medical Physicist with Krueger-Gilbert Health Physics, An Apex Physics Partner. After graduating with her Doctor of Medical Physics degree from Vanderbilt University in 2014, she joined the staff at Krueger-Gilbert Health Physics and has been happily employed there for the last seven years. As a consulting physicist, she works with all types of medical imaging facilities as well as some more uncommon imaging sites such as chicken processing plants, implant manufacturers and recycling facilities. She is an active member of the American Association of Physicists in Medicine and volunteers her time on task groups and committees. Her passion for radiation safety and public education has driven her interests and further fueled her passion for her career in medical physics.
