What procedure is performed to ensure a SPECT camera is functioning properly?

Daily calibration checks are essential for ensuring that a SPECT camera is functioning properly because they assess the camera's performance on a regular basis. Calibration checks involve measuring the camera’s response to known standards and adjusting it accordingly to ensure accuracy and consistency in imaging. This is crucial for maintaining the quality of diagnostic images and ensuring that they are interpretable for clinical use. Daily checks allow for immediate detection of any issues that may arise, enabling quick corrective action to be taken before they affect patient care.

While other procedures mentioned, such as weekly performance audits, monthly image quality evaluations, and quarterly equipment servicing, also contribute to the overall maintenance and quality assurance of SPECT cameras, they typically do not provide the immediate feedback and verification that daily calibration checks offer. Regular calibration ensures that any drift in the camera's performance is identified and corrected promptly, thereby maintaining the integrity of the imaging process.
