AAPM Grand Challenges planned for 2026-27 will be announced soon!
In the meantime, please contact the Working Group on Grand Challenges (WGGC) for any Challenge related questions.
Call for Submissions: JACMP Special Issue
Proposed by AAPM Task Group 379 (organizers of the recently-concluded Grace Kim Memorial Grand Challenge: Advancing Total Body, Marrow, and Lymphoid Irradiation) in collaboration with the AAPM Working Group on Grand Challenges, this Special Issue builds on TG-379's forthcoming report on conventional and intensity-modulated TBI, providing a dedicated forum for clinical implementation, institutional benchmarking, workflow optimization, and emerging innovations. Consistent with JACMP's mission, it prioritizes practical, data-driven contributions with immediate utility for day-to-day clinical practice. Learn more and submit here.
