Imaging Techniques: PET/CT

Price: $15.00
Imaging CE: 2.00
This course is accessible until 12/31/2025

Imaging Techniques: PET/CT is designed to provide imaging professionals and radiation technologists with a basic understanding of the components, theory, use, and benefits of PET/CT technology. It begins with a discussion of the theory and development of PET and CT scanners and the steps that led to merging the technologies to produce PET/CT. Other topics include a brief look at some of the PET/CT systems currently available; the image acquisition process, including whole body scans, heart and brain studies, radiation therapy planning; image formation and reconstruction, list mode theory, as well as acquisition and processing. The final module addresses quality control procedures necessary for maintaining and operating PET/CT equipment.

NOTE for Imaging: This activity may be available in multiple formats or from different sponsors; individuals may not repeat and report a self-learning activity for credit twice in the same biennium. You must be licensed in the state of Florida to report an activity that is only approved by the state.
