Task Group No. 293 - Task Group on Size Specific Dose Estimate (SSDE) for Head CT

AAPM Members, Affiliates and Non-Member Affiliates - Login for access to additional information


The charge of this task group is to develop methods and data to better estimate absorbed dose to the head based upon the CTDIvol computed from the head dosimetry phantom. We will begin by examining existing data and it is anticipated that if the task group is initiated in summer 2016, this TG could be completed by early 2017. Because of the impact of this work on pediatric CT, a pediatric radiologist will join the task group. Of note, pediatric radiologist Kimberly Applegate made this request to John Boone in May 2016.

Most recent status update:Minutes: Task Group 293 – head SSDE Sunday, Nov 26, 2017 9:00 – 11:00 am (scheduled) Meeting started on time with the GOTOMEETING app running. Attendees included: Anthony Hardy, Bob Dixon, Donovan Bakalyar, Thad Wilson, Erin Angel, Mohammed Aljallad, Jia Wang, Nathan Artz, Nima Kasraic, Dianna Cody, Mike McNitt-Gray, Samuel Brady, Keith Strauss, and Pavina Pike. Boone displayed a PPT (on GOTOMEETING) describing the development of the data for the SSDE. This data included physical measurement data made by Sam Brady, Keith Strauss and Nathan Artz, Monte Carlo data from UCLA (Anthony Hardy and Mike McNitt-Gray) and from UC Davis (Andrew Hernandez and Boone). Brain and spongiosum dose was modeled, and after weighting by mass, the combined dose was essentially the same as brain. The data was promising and the TG is on a trajectory for completion in early 2018. We finished a few minutes after 10:00 am. Respectfully, John Boone - [11/26/2017 by John Boone] Click to update.
