An edge-element based finite element model of microwave heating in hyperthermia: method and verification
Bibliographic record
Abstract
Hyperthermia has been shown to improve local tumour control of superficial and deep seated lesions when combined with radiotherapy. There remains difficulty in heating larger tumours with conventional applicators, but this is being addressed by several new applicator designs. This paper presents a new numerical model of microwave heating which is designed to aid in the development of new applicators for superficial heating. The model is based on a finite element method which utilises vector valued basis functions instead of the more conventional scalar valued basis functions. These basis functions were chosen since they are inherently suited for the solution of Maxwell's equations due to their vector nature. The model was successfully verified against an analytic solution to the Mie scattering problem as well as against previously published measurements of heating from a modified water bolus attached to a conventional waveguide applicator. An accompanying paper describes an application of this model to the design optimization of this modified bolus.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
