CT for Technologists
2: Image Formation, Reconstruction, and Artifacts

Format: Online Course
RT Credit: 2.75 ARRT Category A Credits 
Tuition: $27.50

OVERVIEW
The skill of the technologist is the single most important factor in the acquisition of high-quality diagnostic images. A successful CT examination is the culmination of many variables under the direct control of the technologist. Comprehension of CT system components, image formation, image quality, postprocessing techniques, archiving, quality assurance testing, artifacts, and radiation safety is the responsibility of the radiologic technologist to ensure optimal image quality and safe and effective patient care.

CT for Technologists: 2. Image Formation, Reconstruction, and Artifacts introduces the learner to the concepts of the image process, scanning methods, the digital image, image quality, image reconstruction, quality assurance tests, and artifacts. Many factors contribute to image quality, and a thorough understanding of the interactions among these factors will allow the technologist to acquire high-quality, diagnostic images.

EDUCATIONAL OBJECTIVES
After concluding this educational activity, the reader will be able to:

  • List the various types of CT scanning
  • Discuss the interactions of parameters, reconstruction, and evolving technologies of image formation
  • Describe the details that contribute to the digital image and to image quality
  • Discuss image reconstruction and postprocessing techniques
  • Identify the different types and sources of CT artifacts by their characteristic patterns
  • Reduce or eliminate the appearance of artifacts through continual quality assurance and assessment of technical parameters, including phantom testing
