Radiotherapy for brain tumors – New techniques and treatment strategies
Bibliographic record
Abstract
Radiotherapy is generally a local treatment. The radiation oncologist marks image-based the area to be irradiated (targetvolume) as well as areas which should be spared (organs at risk). Three important volumes differ in marking of the targetvolume: gross tumor volume, clinical target volume and planning target volume. Gross tumor volume (GTV) means thevolume where tumor is traceable in CT, MRI, ultrasonic sound, PET or clinical inspection and palpation. Clinical targetvolume (CTV) involves the GTV and the microscopic tumor expansion: peritumoral regions, lymph nodes, perineural orperivascular tumor infiltration, etc. The Planning Target Volume includes the CTV as well as the possible mobility of thetumor and the imprecision in positioning of patients at the linear accelerator. With an exact positioning of the patient at theirradiation device, PTV margin can be considerably reduced. That leads to a reduction of exposure in the healthy tissue andto a dose weighting in the tumor area.

How this classification was reachedexpand
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.
