Abstract
Background: The radiographic film interpretations are evaluated by viewing the radiographic films placed in an illuminator. Therefore, the intensity and uniformity of the illuminator should be maintained throughout. Objective: To evaluate the intensity and uniformity of the illuminators. Materials & Methods: The radiographic illuminators, which used in the Department of Radiology, Maharat Nakhon Ratchasima Hospital, were studied by using lux Meter to measure brightness at specific locations on the surface of the illuminator. The mean of the intensity of brightness from these locations was compared with German DIN 6856 standard. Result: 63 Illuminators were evaluated. Average intensity of brightness was 821±227.38 cd/m2 (range 347.6-1,460.4 cd/m2). 17 radiographic illuminators (26.98%) had uniformity of brightness as German DIN 6856 standard. Conclusion: The radiographic illuminators, in the Department of Radiology, Maharat Nakhon Ratchasima Hospital, had the intensity of brightness below German DIN 6856 standard and uniformity of brightness as German DIN 6856 standard (± 30%) 26.98 percent.
