What three items should be monitored by the Processor Quality Control program?

In the context of a Processor Quality Control program, it's essential to monitor parameters that directly affect the quality and consistency of radiographic films. The combination of base-plus fog density, mid-density, and density difference provides a comprehensive overview of the film processing conditions and image quality.

Base-plus fog density measures the inherent density of the film plus any additional density contributed by the processing system and ambient conditions, providing a baseline from which to evaluate film performance. Mid-density helps in assessing the overall exposure level of the radiographic film, ensuring that the film is adequately exposed to capture the necessary details. Density difference is crucial as it indicates contrast and the ability to distinguish between different materials in the radiograph. Monitoring these three items allows for an effective quality control process that can identify when adjustments are needed to maintain optimal processing conditions, which is vital for producing high-quality radiographic images.

In contrast, the other options contain elements that may not directly align with the most critical aspects of film processing quality control in radiography. For instance, while some of the components in those options provide relevant data, they do not encompass the essential parameters required to effectively monitor and control the processing quality of radiographic films.
