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.

Timothy Szczykutowicz is an associate professor in the University of Wisconsin School of Medicine and Public Health Departments of Radiology, Medical Physics and Biomedical Engineering. His clinical and research activities include: optimizing CT scan protocols, monitoring patient dose, developing new metrics to define image quality in the clinical setting, developing protocol management methodologies, fluence field modulated CT, dual energy CT, and radiology department workflow and quality metrics.

Timothy is also the author of the book The CT Handbook: Optimizing protocols for today’s feature-rich scanners. He is an associate/section editor or on the board for multiple journals including: Medical Physics, Radiographics, Contemporary Diagnostic Radiology, and the Journal of Computer Assisted Tomography.
