Measured kVp should be within what percentage of the kVp indicated on the console?

In quality control for radiographic equipment, the accuracy of the kilovolt peak (kVp) indicated on the console is critical for ensuring optimal image quality and patient safety. The acceptable range for the measured kVp compared to the indicated kVp typically falls within 5%. This standard helps to ensure that the x-ray beam produced is of sufficient energy for penetrating tissue while minimizing unnecessary radiation exposure. A deviation greater than this tolerance could result in images that are either underexposed or overexposed, affecting diagnostic quality and potentially leading to repeated examinations, which further exposes patients to radiation. Thus, maintaining a 5% accuracy standard is essential in routine quality control assessments.
