This session gives a detailed description of the construction and function of a digital gamma camera for planar radionuclide imaging.


By the end of this session you will be able to:
• Identify the components of a gamma camera and describe their function
• Recognise the difference between different types of collimator
• Describe the technology and processes involved in image production and correction
• Identify the interactions that occur between gamma photons and a sodium iodide scintillation detector and describe how scintillation light is produced
• Describe how photomultiplier tubes detect scintillations and convert them into electrical signal pulses
• Recognise the spectrum of absorbed energy values and describe how photopeak counting is used to reject much of the scattered radiation
