Abstract

fetched live from OpenAlex

Ultrasound imaging of brain tissue features and abnormalities is notoriously difficult through the skull because of the high attenuation and skull-induced phase aberration. A custom-designed transcranial matrix probe with a novel adaptive beamforming method has been developed at Tessonics Inc., Windsor, Ontario. The technology corrects for skull-induced distortions in the reconstructed sonograms. The current goal is to diagnose intracranial hemorrhages with the motivation of reducing the time between an injury and appropriate aid. In emergency situations, a portable point-of-care device may save vital time and reduce fatalities. Conventional screening methods, like computed tomography, do not offer the portability, low-cost, and non-ionizing radiation benefits that ultrasound imaging provides. Ultrasonography is also non-invasive and allows for real-time imaging. The analysis of the acoustic field for the ultrasound probe is an integral part of device development. Standards for ultrasound machine intensity output must be met to eliminate the risk of damage to body tissues. Simulations of the acoustic field are created through the Fast Object-oriented C++ Ultrasound Simulation (FOCUS) software based on desired focal points. The measurements and simulations presented in this work will ensure patient safety for future testing.

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.
