Perbandingan densitas optik dan kontras Radiograf yang dihasilkan pesawat sinar -X jenis konvensional dan kondensator

Abstract

Keluaran sinar-X ditentukan oleh tegangan, arus, jarak antar¬elektroda dan filter. Perbedaan catu daya tegangan tinggi untuk menghasilkan sinar-X (seperti pesawat sinar-X konvensional dan pesawat sinar-X kondensator) akan menyebabkan perbedaan keluaran sinar-X, dan dapat dianalisis dengan mengukur skala densitas optiknya menggunakan densitometer serta menghitung skala kontras pada film radiograf. Hasil penelitian menunjukkan bahwa: 1. Pesawat sinar-X konvensional mempunyai skala densitas optik radiograf lebih besar daripada pesawat sinar-X kondensator. 2. Pesawat sinar-X kondensator mempunyai skala kontras radiograf lebih besar daripada pesawat sinar-X konvensional. Kata kunci: pesawat sinar-X konvensional, pesawat sinar-X kondensator, skala densitas optik radiograf dan skala kontras radiograf. X-rays output was characterized by voltage, current, inter-electrodes, distance and filter. The differences at the high voltage supply which produce X-rays (such as the conventional X-rays and the condensator X-rays machine) will cause different output intensity and can be analyzed by measuring its optic density scale by densitometer and calculating its contrast scale on the radiograph film. The result of the research shows that: 1. The conventional X-rays machine have to radiograph optic density scale radiograph larger then the condensator X-rays machine. 2. The condensator X-rays machine have to radiograph contrast scale radiograph larger then the conventional X-rays machine. Key words: conventional X-rays, condensator X-rays, optic density scale and contrast scale radiograph. This document is Undip Institutional Repository Collection.
