Desing and realization of a computer-assisted nephrostomy guidance system
Bibliographic record
Abstract
Background and purpose: Nowadays, computerized nephrostomy techniques exist. Although relatively safe, several factors make it difficult for inexperienced users. A computer-assisted nephrostomy guidance system has been studied to increase the success rate of this intervention and reduce the work and difficulties encountered by the actors. Methods: To design the system, two methods will be studied. Following this study, this system was designed based on method 2. SmartSysNephro is composed of a hardware part whose manipulations made by the user are visualized and assisted by the computer. This nephrostomy procedure that the user simulates is monitored by webcam. Using the data from this Intel Real Sense webcam, allowed to propose a CNN YOLO model. Results: The results obtained show that the objectives set have been achieved globally. The SmartSysNephro system gives real time warning when the surgeon deviates from the standard workflow. It allows monitoring of the nephrostomy procedure via webcam. It is therefore relying on tracking, and it also has the potential to identify workflow tasks in video using the YOLO model. Conclusion: SmartSysNephro shows that the skills of the users can be greatly improved during the intervention because they will benefit from the assistance of the end-to-end system. Therefore, the success rate of nephrostomy increases, and the difficulties encountered by the actors decrease considerably.

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.
