What is assessed by the 'Output of Tube' during daily CT quality control?

The assessment of the 'Output of Tube' during daily CT quality control involves measuring the tube intensity at various kilovolt peak (kVp) settings and milliampere-seconds (mAs). This test is essential because it helps ensure that the CT scanner is delivering consistent and accurate radiation output, which is critical for obtaining high-quality images. By evaluating the output at multiple settings, technicians can detect any irregularities or fluctuations in the tube's performance, such as variations in intensity that could affect image quality or patient safety. Monitoring these parameters allows for adjustments to be made promptly if discrepancies are found, maintaining the overall functionality and reliability of the CT scanner.
