AI-Enhanced SDR Microwave Breast Cancer Screening Transceiver: A Comparative Study
Bibliographic record
Abstract
Microwave transceivers play a crucial role in microwave breast screening systems, significantly influencing the final product performance, cost, and form factor. This article presents a portable and economically viable yet high-performing microwave transceiver designed based on the software-defined radio (SDR) architecture. This transceiver is intended to complement a switching matrix and antenna array, forming a novel microwave breast cancer screening prototype. This new system aims to replace two older transceivers, which are included in this study for comparative analysis. The comparison is conducted on a purposely designed test bench against a commercially available vector network analyzer (VNA) used as the benchmark. In addition, this VNA serves as a reference for training a denoising autoencoder neural network, aimed at enhancing the signal integrity of the new prototype. Comparative evaluations are performed across the time domain, frequency domain, and delay-multiply-and-sum (DMAS) image domain. The findings reveal that the SDR-based prototype achieves satisfactory and comparable imaging results, all while costing a fraction of the price of alternative systems.

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.
