Ultrasound mediated study of the electrokinetic effects in biological tissues and phantoms
Bibliographic record
Abstract
Traditional ultrasound imaging monitors the backscattering properties of the object being imaged. Many hybrid imaging techniques such as photo-acoustic imaging, electro-acoustic imaging etc. have been developed to enhance the contrast in imaging. The main objective of this study was to monitor the electrically induced mechanical changes (EIMC) in ultrasound phantoms. Changes in time shifting of the signals and amplitude changes were investigated. Images were formed using a linear array ultrasound probe based on the time-delay estimates and the amplitude changes occurring in the tissue/phantom structure. EIMC in phantoms were found to depend on the applied electric field, gelling agent concentration, and salt concentration. The dependence of EIMC on the various parameters can be explained by the stiffness and fixed charge densities (FCD) of the phantoms. Knowledge gained from experimental results and its future extensions might culminate to form a method to image tissues based on their electrokinetic properties.

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.
