AAPM task group 241 – MR-guided focused ultrasound


Task Group (TG) 241 of the American Association of Physicists in Medicine (AAPM), operating under the Work Group for Technology Assessment in Image-Guided Interventions, was formed in September of 2013 with an international membership of experts from MR-guided focused ultrasound (MRgFUS), focused ultrasound and ultrasound physics, radiation oncology, industry and federal agencies.

The charge of TG-241 is to report through peer-reviewed publications on the assessment of state-of-the-art clinical MRgFUS technology, including the intrinsic system characteristics, quantitative metrics, sources of uncertainty, quality assurance measures, data types and nomenclature as well as training issues for medical physicists.


In addition, through related sub-group activities, TG-241 will consider development of an open tool as a public resource for the MRgFUS research community.

Results and conclusions

The goal of this presentation is to introduce TG-241 to the research community and solicit input about its current activities and future directions.
