Abstract
PET/CT is a routinely performed diagnostic imaging procedure. To ensure that the system is performing properly and produces images of best possible quality and quantitative accuracy, a comprehensive quality control (QC) program should be implemented. This should include a rigorous initial acceptance test of the system, performed at the time of installation. This will ensure the system performs to the manufacturer’s specifications and also serves as a reference point to which subsequent tests can be compared to as the system ages. Once in clinical use, the system should be tested on a routine basis to ensure that the system is fully operational and provides consistent image quality. To implement a successful and effective QC program, it is important to a have an understanding of the basic imaging components of the system. This chapter will describe the basic system components of a PET system and the dataflow that will aid a user in identifying potential problems. Acceptance tests and QC procedures will also be described and explained, all designed to ensure that a consistent image quality and quantitative accuracy are maintained. As will be discussed, an effective QC program can be implemented with a few relatively simple routinely performed tests.
