In the context of computed tomography (CT), the term 'scan date' specifically refers to the time when a patient undergoes the imaging procedure and the data collection begins. This is crucial as it marks the moment when the raw data from the scan starts to be recorded. This raw data includes all the information gathered by the CT machine as it takes images from multiple angles, which is subsequently used to create detailed cross-sectional images of the body.

Understanding raw data is essential because it is the foundation from which processed images are derived. Processed data and image quality metrics usually come into play after the raw data has undergone various reconstruction algorithms and quality assessments. Additionally, while patient details are important for identifying the scan and ensuring appropriate care, they do not pertain to the actual imaging data being captured.

Hence, identifying 'scan date' with raw data highlights its role in the imaging process, establishing why this particular choice is the most accurate in the context of CT scanning.
