Are the positron-emitting radionuclides higher-energy emitters than single-photon radionuclides? How are nuclear medicine images obtained? Like a plain radiograph, nuclear medicine produces a 2-dimensional image. How can information on depth be obtained? Provide half-life Provide half-life and photon energies for the following The gamma camera system consists of a collimator, a sodium iodide crystal, photomultiplier tubes, and a computer. What is the function of each of these components in the system? What are planar images? What are the units of activity? What is SPECT? What is activity? What is nuclear medicine? What is the advantage of SPECT? What is the disadvantage of SPECT?
