Which quality of detectors is evaluated by the daily QC tests in CT scans?

The evaluation of uniform sensitivity of detectors in daily quality control (QC) tests for CT scans is crucial for ensuring consistent image quality and accurate diagnostic information. Uniform sensitivity indicates that each detector in the array is responding similarly to X-ray radiation, which is essential for capturing clear and reliable images. Variations in sensitivity between detectors can lead to artifacts and discrepancies in the reconstructed image, potentially affecting the diagnostic outcomes.

Regular assessments of uniform sensitivity help in identifying any deviations that may occur due to factors like wear and tear, calibration drift, or environmental changes. By confirming that detectors maintain a uniform response, the accuracy of the images produced by the CT scanner is upheld, leading to better patient care and treatment decisions.
