Task Group No. 211 - Classification, Advantages and Limitations of the Auto-Segmentation Approaches for PET

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

Charge

1. Provide a classification of the PET segmentation methods based on their assumptions, algorithmic approach, detail, complexity and goal. Provide information on the advantages, limitations and applicability of each class of methods based on the limitations imposed by their assumptions and on current literature. Consider the different applications of interest such as "dose painting" or simpler functional volume definition for radiotherapy treatment planning, or volume changes in treatment with PET. 2. Draft a list of minimum requirements which PET segmentation methods should satisfy, as well as acceptance and implementation procedures for these methods. 3. Propose a protocol for evaluation of current and future segmentation methods based on a general framework [39], which will be expanded and adapted to PET imaging [40].

Most recent status update:The task group report was approved by the AAPM Science Council in May 2016 and was submitted for publication to the Medical Physics Journal in the first week of June. The group is currently working towards generation of a standard for evaluation of PET auto-segmentation methods and a paper and a proposal for a second report are in preparation. - [6/16/2016 by Assen Kirov] Click to update.
