Task Group 233 provides new guidance for CT performance assessment and addresses the challenges inherent in established CT imaging quality metrics. The Mercury 4.0 Phantom, designed by Dr Ehsan Samei at Duke University and commercialized by Gammex, now Sun Nuclear Corporation, assists with evaluations outlined in TG-233.

During this webinar, Timothy Szczykutowicz, PhD, DABR, of the University of Wisconsin-Madision, Department of Medical Physics, will present on how his department uses the Mercury 4.0 Phantom for common clinical CT tasks. You will hear about how the Mercury 4.0 Phantom addresses advanced features including automatic exposure control and tube current modulation. This webinar will enable you to understand how this new phantom lets the user check patient size for protocol optimization and proper dose management.
