This curated series from the most recent annual meeting of the Radiological Society of North America highlights a selection of education exhibits dealing with radiation safety and patient dose. New exhibits are added monthly.
Apr. 14, 2017 — A Comprehensive CT Radiation Dose Reduction and Protocol Standardization Program in a Complex Tertiary Hospital System (from RSNA 2016)
The Joint Commission requires the radiation dose of every CT exam to be recorded with investigation of cases where radiation dose exceeded established reference levels. The authors present their experience in instituting a radiation dose reduction program in a large complex health system using a novel web-based information distribution system and iterative process of lowest common denominator using phantom and clinical test cases prior to implementation.

Mar. 27, 2017 — Whole Body CT Protocol for Trauma: Review of Arm Positioning with Emphasis on Image Quality and Radiation Dose (from RSNA 2016)
The authors review the influence of different arm positioning on image quality and radiation dose at whole-body CT for trauma and discuss optimal strategies to minimize beam hardening artifacts and reduce radiation dose when a patient’s arm cannot be moved up.
