Pengaruh peningkatan tegangan Tabung Sinar X terhadap Kontras Radiografi dan laju Dosis Radiasi
Bibliographic record
Abstract
Telah dilakukan penelitian tentang pengaruh peningkatan tegangan tabung sinar-X terhadap kontras radiografi. Peningkatan tegangan tabung sinar-X menyebabkan perbedaan sinar-X yang ditransmisikan oleh obyek, sehingga menghasilkan densitas yang dan kontras radiograf yang berbeda. Pengaruh peningkatan tegangan tabung sinar-X terhadap kontras radiograf diperoleh melalui pengukuran densitas radiograf setelah sinar-X menembus stepwedge. Perbedaan kehitarnan (densitas) pada stepwedge setiap kenai.kan tegangan tabung menghasilkan kontras radiograf. Untuk mengetahui pengaruh peningkatan tegangan tabung sinar-X terhadap dosis radiasi yang diterima oleh pasien, dilakukan melalui pengukuran laju dosis radiasi hambur. Hashl penelitian meriunjukkan, semakin tinggi tegangan tabung sinar-X, kontras radiograf yang dihasilkah rendah, tetapi dosis radiasi yang diterima oleh pasien iebih kecil. Kata kunci : tegangan tabung (kV), densitas radiograf, kontras radiograf, laju dosis radiasi hambur dan dosis total pasien. It has been researched about affect increasing X-ray potential tube to radiographic contrast. Increasing X-ray potential tube causing defference radiographic density and radiographic contrast. Affect increasing X-ray potential tube to radiographic contrast had to measurement radiographic density which transmitted to stepwedge. Density deference of stepwedge at X-ray potential tube increasing results radiographic contrast. For understanding to affect X-ray potential tube for patient radiation dose have measurement by scattering rate dose. The result of experiment the higher X-ray potensial tube make the lower radiographic contrast, and decrease the patient dose. Key word : potensial tube (kV), radiograph density, radiograph contras, seater radiation dose rate and patient total dose.

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.
