NMTEC 202 Instrumentation • 3 Cr.
Examines the function and use of the nuclear medicine gamma camera. Topics include basic electronics, collimators, digital cameras, on-line correction systems, and modifications required for tomographic studies. Students learn quality control and troubleshooting. Also includes positron emission tomography. Prerequisite: Acceptance into program.
Prerequisite: Acceptance into the program.
After completing this class, students should be able to:
- 1. discuss how gamma cameras have changed since their invention, particularly as relates to determination of gamma ray position, image display, and uniformity correction.
- 2. define and discuss the impact on planar images of: third-dimension integration, background, noise, attenuation, scatter, and patient motion; define contrast and discuss how the above factors affect it.
- 3. discuss the manufacture, mathematics, and uses of various kinds of collimators, including the design characteristics that make them good for specific purposes.
- 4. discuss how planar images can be improved, from the standpoints of spatial resolution, noise, and imaging time, and the trade-offs that come with each option for improvement.
- 5. describe routine and non-routine quality control for gamma cameras and identify artifacts seen on planar images.
- 6. describe acquisition and display of SPECT images.
- 7. explain the reconstruction processes used in SPECT imaging and evaluate SPECT images for artifacts.
- 8. discuss the need for attenuation correction and methods by which it is implemented.
- 9. outline techniques used to improve SPECT images, in regard to both acquisition parameters and reconstruction choices.
- 10. explain the physics and concepts behind acquisition of PET imaging.
- 11. identify the required QC testing for SPECT and PET systems.
- 12. discuss ways that SPECT and PET images are quantitated, and the limitations of those methods.
- 13. briefly discuss the basic operation of a CT system and its application to nuclear medicine studies.
