Continuous monitoring of cervical dilatation and fetal head station during labor
Bibliographic record
Abstract
An ultrasound-based computerized system was developed for monitoring cervix dilatation and fetal head station during labor. The system was designed to provide continuous and accurate assessment of the progression of labor. The computerized labor-monitor (CLM) was tested in the laboratory and was studied in over 95 women during labor. The laboratory test showed that the mean error of measurement is 0.1 mm with standard deviation of 1.14 mm. In the clinical experiments, safety of the various system components was demonstrated and partograms were compared to manual measurements. The systematic error of the fetal head station measurement is estimated as 10-20%, depending on patient's anatomy. In addition, the clinical tests indicated that measurements of the changes of both cervix dilatation and fetal head station are feasible. The CLM is expected to change patient management in the labor room. It will enable timely recognition of abnormal labor patterns such as dysfunctional and precipitous labor. Continuous accurate data will allow earlier diagnosis and intervention that is very likely to improve both mother's and baby's clinical outcome.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
