Abstract

fetched live from OpenAlex

The recently proposed concept of composite tissue-type image (cTTI), which provides an easy-to-interpret image constructed from quantitative ultrasonic and electromagnetic properties, is experimentally investigated. The experimental data set used for the ultrasound investigation is obtained from the multimodal ultrasound breast imaging system. The experimental data set utilized for microwave imaging is provided by an inhouse system at the University of Manitoba. To this end, a tissue mimicking phantom and a human forearm are utilized for experimental ultrasound and microwave imaging. In addition, the cTTI algorithm is modified to take into account differences in the quantitative accuracy of reconstructing one property compared to other properties so as to increase the achievable accuracy in the resulting cTTI. In addition to experimental ultrasound and microwave data, the cTTI method is also applied against synthetic data obtained from an MRI-based numerical breast phantom to further demonstrate the performance of the cTTI not only with respect to microwave and ultrasound tomography data but also with respect to their combination. Finally, the improvements of the cTTI reconstructions based on changing the prior probabilities compared with equal prior probability distribution are shown for combined ultrasound and microwave tomography of a numerical breast phantom.

Teacher imitation

Not 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.
