Introduction to Emission Tomography

This lecture covers the fundamentals of emission tomography in biomedical imaging, focusing on examples of human brain and heart imaging using radiotracers, as well as the basic elements required for gamma-emitter imaging. The instructor explains the concept of emission computed tomography, the injection of radioactive tracers, and the equipment needed for gamma-emitter imaging. Various examples are provided, such as Thallium SPECT scans for CNS lymphoma and Alzheimer's disease imaging. The lecture also discusses the importance of tracers with specific half-lives and photon energies for emission tomography.
