NMTEC 203 Computers in Nuclear Medicine • 3 Cr.
Introduces the use of computers in nuclear medicine, emphasizing analysis of static, dynamic, and tomographic images. Prerequisite: Acceptance into program.
After completing this class, students should be able to:
- Explain the basic structure of a computer, including the essential components and their interactions.
- Discuss the advantages and disadvantages of various computer storage devices, especially those commonly used in nuclear medicine.
- Describe the ways in which computers can be networked together, the benefits of such networking, and the basic workings of the largest network, the Internet.
- Define PACS, RIS, and accession number, and discuss how these are used in nuclear medicine practice.
- Describe how a nuclear medicine image is stored in a computer, including the concepts of pixels, counts/pixel, and analog to digital conversion.
- Describe and discuss advantages and disadvantages of each of the following types of image acquisition methods: frame mode, byte mode, dynamic frame mode, multiple gated mode, and list mode.
- State the purpose of a buffer in nuclear medicine image acquisition.
- Describe five image enhancement methods used in nuclear medicine, including their methodology and advantages/disadvantages.
- Discuss the use of regions of interest in the quantification of both static and dynamic images.
- Describe how time-activity curves may be generated and manipulated.
- Explain the generation and usefulness of the left ventricular ejection fraction, the volume curve, first and second derivative curves, phase analysis, and amplitude analysis in gated cardiac studies.
- Discuss the acquisition and data processing of first pass studies, including both ventricular function studies and intracardiac shunt studies.
- Explain how a series of nuclear medicine images can be reconstructed into a 3-dimensional image, and describe both filtered backprojection and iterative reconstruction methods.
- State the purpose of filtering in SPECT imaging, and describe the different filter types commonly applied to SPECT images.
- Discuss the application of quantitative programs to SPECT studies, particularly for the heart.
