Which scan is used for quality control in PET that involves transmission data?

The scan used for quality control in PET that involves transmission data is the Blank Scan. In the context of PET imaging, a Blank Scan is performed to assess and calibrate the system's response to radiation. This type of scan allows for the evaluation of the detector's sensitivity and uniformity across the field of view without the influence of radiopharmaceuticals.

During a Blank Scan, the system records the detection of background radiation and any electronic noise, providing a baseline measurement. This information is crucial for ensuring the accuracy and reliability of subsequent PET scans, where specific imaging agents will be utilized. By comparing the data obtained during the Blank Scan to subsequent scans, technicians can correct for any inconsistencies or abnormalities, leading to improved image quality and reliable diagnostics.

Dynamic scans, contrast scans, and stress scans serve different purposes in imaging protocols, such as evaluating physiological responses, assessing blood flow, or highlighting specific structures. However, they do not primarily focus on the quality control aspects related to the transmission data as the Blank Scan does.
