Which item is included in daily Processor QC checks related to temperature?

• A. Wash Water & Developer TEMPERATURE
• B. Film speed
• C. Exposure time
• D. Plate alignment

Answer: (A)

Temperature control during film processing is essential because chemical activity in the developer depends strongly on temperature. When the developer runs at its specified temperature, the development rate is predictable, giving consistent film density and contrast from one film to the next. If the developer temperature drifts high or low, images can become uniformly too dark or too light, and contrast can shift, compromising diagnostic quality. The wash water temperature also matters because it affects how well residual chemicals are removed; improper wash water temperature can lead to incomplete rinsing or artifacts. So, daily Processor QC includes checking both the wash water and the developer temperatures to ensure the processor operates within its intended range. Other items like film speed, exposure time, or plate alignment relate to other aspects of imaging quality and QA and are not temperature checks in this context.
