What indicates that a sensitometry strip is being conducted correctly?

  1. Consistent daily readings

  2. Excessive variations in exposure

  3. Unpredictable density results

  4. Improper handling of film

The correct answer is: Consistent daily readings

The indication that a sensitometry strip is being conducted correctly is shown by consistent daily readings. Sensitometry is a practice used to evaluate the response of radiographic film to exposure and processing. Consistent readings over time suggest that the exposure parameters and processing conditions are stable. This stability is essential for ensuring the reliability of radiographic results, as it indicates that the film is responding predictably to known levels of exposure. When the readings are consistent, it reflects proper calibration and maintenance of the imaging system, as well as adherence to protocols during film processing. This consistency enables radiologic technologists to establish a baseline for the film and make informed decisions about exposure adjustments, ultimately improving the quality of diagnostic imaging. In contrast, excessive variations in exposure, unpredictable density results, or improper handling of film would indicate potential issues in the sensitometry process. Such issues could lead to unreliable results and could compromise the diagnostic quality of the radiographs being produced.
