X ray film viewer position and notice in operating room

X ray film viewer should be set in operating room according to need. To keep clean, save space and convenient for surgeon observe, film viewer is generally located opposite the surgeon, generally use wall mounted installation, flush with the wall front, seal the seams with glue, or stainless steel flange on the four sides, the convenience of internal light source replacement should also be considered into.

X ray film screen can be chosen according to operating room size, and confirm it with professional medical staff, generally 3-5 screens is much popular (considering clamping diagnostic film and reference standard film at the same time). Regardless of the screen number of wall mounted film viewer, mostly its height is between 400-600mm, taking into account the standing position observation, film viewer installation height is 1300-1400mm from the film viewer’ bottom edge to the ground. For multi-screen X ray film viewer, each screen light is controlled separately, the switch is always on the control panel below the viewer.

The brightness of medical X ray film viewer has an important impact on the diagnostic quality of X-ray films. Low brightness film viewer can capture the density of film images recorded, leading to misdiagnosis or missed diagnosis, therefore, the highest brightness in film center should not be less than 4200cd / m2, observation screen brightness difference should not exceed 15%. When high brightness is needed (for observation of high-density X-ray film), the light box should be equipped with bright light.

Using continuous adjustable light control is much better for operating room X ray film viewer (including light source and bright light), there are 2 reasons: 1. There will be many different surgeries in general hospital operating room, adjustable light brightness film viewer can suit reading different optical density of X-ray film. 2. Operating light has high brightness, adjustable brightness film viewer can balance the external light for reading environment. Besides, it should be noted that other light sources should not light the film viewer directly, avoiding reducing the reading effect.
