Measurement of effective dose to patient during interventional cardiac procedure
Bibliographic record
Abstract
Interventional cardiac procedures result in substantial patient radiation dose due to prolonged fluoroscopy time and radiographic exposure. Patient dose measurement is performed in two catheterization laboratories in Square Hospital Ltd, Dhaka. A total of 50 patients of Square Hospital is included in this study. TLDs are used for the measurement of the dose received by patients during interventional cardiology at Square Hospital, Dhaka. Patients, who underwent CAG, PTCA, and (CAG with PTCA) have average effective dose 3.30 mSv with a range from 0.96 to 9.12 mSv, 24.14 mSv with a range from 7.56 mSv to 56.81 mSv and 25.56 mSv with a range from 1.21 mSv to 95 mSv respectively. Our results correspond well with those obtained by authors in other countries of the world. This study would be useful to establish a database of the patients dose for CAG and PTCA. This may lead cardiologists and scientists to adopt necessary safety measures for reducing exposure to patients and occupational workers.J. Asiat. Soc. Bangladesh, Sci. 40(1): 1-7, June 2014

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.
