Nuclear medicine instrumentation, physics, and quality control are fundamental core concepts for the accurate interpretation of nuclear medicine imaging. Due to their complexity and differences from other topics in radiology, these topics may be difficult to grasp for many trainees. This exhibit seeks to bridge this gap and provide a working introduction to these concepts.

Educational Goals / Teaching Points
This exhibit will introduce trainees to the fundamental concepts underlining nuclear medicine physics, instrumentation, and quality control. Trainees will review the fundamental modes of decay and how they are used in different nuclear medicine techniques. Furthermore, this exhibit will review and contrast the basics of image acquisition systems and review basic functioning and uses of common non-imaging instrumentation. Finally, we will review key concepts in quality control and basic sources of commons artifacts.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The exhibit is divided into four main parts: introduction to nuclear medicine physics; imaging instrumentation; non-imaging instrumentation; and quality control. The physics section will provide a review of different types of nuclear decay, with examples of common applications of each and schematics explaining the relevant details of each decay scheme. This section will transition into imaging instrumentation, applying these physics concepts to compare and contrast the fundamental components and basics behind planar SPECT and PET systems. The non-imaging instrumentation section will highlight other key components in nuclear medicine beyond imaging detectors, showcasing devices such as survey instruments (Geiger counter, well counters), cyclotrons, and generators. Labeled diagrams and images for each device will be included, as will summaries of their applications. Finally, the quality control (QC) section will summarize standard protocols fundamental for the ongoing maintenance of nuclear medicine systems. Standard metrics such as spatial resolution, field uniformity, and linearity, among others, will be highlighted. Examples of testing phantoms and procedures will also be included, with standard schedules for the maintenance of each system delineated. Common artifacts and failed QC tests will also be included.

The technical aspects of nuclear medicine (including physics, instrumentation, and QC) constitute critical topics for nuclear medicine understanding. This exhibit will provide a practical introduction to these concepts, equipping trainees to understand the nuisances behind nuclear medicine image acquisition.
