Instrumentation and Radiopharmaceuticals

  1. Identify the process on how radiation is detected with gas-filled detectors.
  2. Discuss the characteristics of Ionization between the ionization region and the GM Region.
  3. What is scintillation?
  4. Consider the method of scintillation detections. Understand the process. Draw the components.
  5. What are the setting for 123I if the window as set to 20%? (159 keV)
  6. Name the different types of collimators and define the specific characteristics of each (HR, HS, Converging, Diverging, and Pinhole).
  7. When you distance between the patient and the detector you increase scatter. Why is this a true statement?
  8. What are the components that would make up an ideal radiopharmaceutical?
  9. Identify the different physiological methods in which a radiopharmaceutical is picked up by an organ or disease state (there are 9),
