Abstract

fetched live from OpenAlex

In this review the current status of absorbed dose to water standards for high-energy photon beams (60Co—50 MV nominal accelerating potential) is discussed. The review is focused on calorimeter-based absorbed dose standards for photon radiation therapy calibrations with typical dose rates of a few gray per minute. In addition, two alternative types of absorbed dose standards are also discussed. The overall uncertainty on measured dose to water in static reference fields is nowadays on the order of 0.4% to 0.5%. The components contributing to the uncertainty budgets are discussed. The discussed absorbed dose to water standards are expected to continue to have their place not only in the dissemination of absorbed dose to water but also in the determination of beam quality conversion factors essential in reference dosimetry in high-energy photon beams.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
