Design of a minimally invasive single port HDR brachytherapy applicator for the treatment of lung cancer
Bibliographic record
Abstract
Cancer has become the number one cause of death in Canada and lung cancer is its deadliest form. Surgical resection remains as the treatment of choice for most patients; however, in many cases a less aggressive alternative such as brachytherapy may be preferable. Today, HDR brachytherapy is a relatively common procedure but with current techniques and equipment only tumours close to the main bronchi can be reached.\nThis project describes the design, development and validation of a first prototype of an ultrasound-guided needle guidance system that would enable physicians to perform HDR brachytherapy for the treatment of lung cancer in a minimally invasive manner through the intercostal spaces. The development of the mechanical components is thoroughly described followed by the description of the electronic control system that was developed for this novel mechatronic medical tool. Finally through validation experiments, the approach was shown to be an accurate and viable approach for precisely reaching desired targets with a wide yet flexible needle.

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.
