How frequently should focal spot size, KVP accuracy, and exposure time accuracy be checked?

The frequency for checking focal spot size, KVP accuracy, and exposure time accuracy is typically set to occur annually. This timeframe aligns with industry standards and best practices for quality assurance in radiography. Checking these parameters on an annual basis allows facilities to ensure that their equipment remains within acceptable performance limits while also managing workflow and operational efficiency.

Annual checks are essential for maintaining the overall quality of radiographic images by ensuring that the equipment is functioning correctly and producing consistent results. While more frequent checks may be necessary in some high-usage environments or for specific regulatory requirements, an annual review is generally sufficient for most facilities to detect any significant deviations from the established standards and make necessary adjustments or repairs.

Regular monitoring not only enhances image quality but also contributes to patient safety by minimizing the risk of repeated exposures due to equipment malfunction or inaccuracies.
