AAPM Committee Tree

The goal of this task group is to develop guidance and recommendations for recovering from fault states in radiation therapy, specifically regarding conventional delivery of photon or electron beams using a linear accelerator. The following topics will be included in the report:

1. A framework to relate fault states (warning and error messages) with pathways leading to data corruption or loss. Recommendations to users on what items need to be checked or verified after a fault to ensure that the patient is treated as planned.
2. An approach to error codes, their meaning, and the state that triggers them. This will include a discussion of the consequences if the user chooses to ignore an error message and consideration of how this complements the ROSSI efforts. 
3. The importance of understanding the data folder tree structure and caching used by the software so that users can verify the integrity of data using time stamps, check sums, or other methods.<
