RF Radar Breast Health Monitoring: System Evaluation With Post-Biopsy Marker
Bibliographic record
Abstract
This work reports on the first systematic experimental study on tissue phantoms that evaluates the efficacy of the radiofrequency (RF) multistatic radar for breast health monitoring in the presence of a titanium site marker, typically inserted post-biopsy. We show results of breast phantom measurements for a homogenous fat phantom in several scenarios: all-fat phantom simulating a simple healthy case, a case with an added small 1 cm diameter tumor, a case with a glandular insertion, and finally, a scenario of a tumor embedded in gland. To evaluate the system's performance with respect to post-biopsy site markers, we then show investigations of the system performance with the same phantom and a biopsy marker attached to a glandular insertion with and without an embedded tumor, and compare the imaging results to those phantoms without the biopsy marker. We conclude that our RF radar can detect the tumor despite the presence of a biopsy site marker, and that the conductive titanium marker does not interfere with the system's intended function.

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.
