CAT 233 - Introduction to Physics and Instrumentation of CT

CAT 233 - Introduction to Physics and Instrumentation of CT This course includes registry prep with a strong emphasis on physics due to the historically low scores on the ARRT registry in the physics category. The content is designed to impart an understanding of the physical principles and instrumentation involved in computed tomography. Course Outcomes: ASRT Outcome 01: Discuss computed tomography radiation physics. ASRT Outcome 02: Describe CT system principles, operation, and components. ASRT Outcome 03: Describe CT system image processing. ASRT Outcome 04: Explain CT image display. ASRT Outcome 05: Describe the computed tomography informatics systems. ASRT Outcome 06: Describe image quality in computed tomography. ASRT Outcome 07: Recognize computed tomography artifacts and explain reduction techniques. Course Outcome 01: Illustrate knowledge of the computed tomography equipment components. Course Outcome 02: Explain the physical principles of computed tomography. Course Outcome 03: Explain the interaction of x-rays with matter as to the formation of the CT image.

Quality Note:
This course was subjected to a six step review process: 1. A SME creates the outline and all content. The course is submitted to a course developer for implementation into the CANVAS LMS system. Areas of confusion or items that need additional clarity are identified and remediated. 3. An instructional design checklist is applied to ensure ADA, UDL, and Creative Commons compliance. 3. Course is reviewed using a modified Quality Matters Rubric. 4. The initial offering is by the original SME to identify other necessary revisions. 5. Course goes through a secondary Quality Improvement process evaluation by an Instructional Designer and is subject to a Quality Improvement checklist. 6. Course is reviewed by third-party evaluator acting in the role of a SME.
Quality of Subject Matter was assured by:
  • Consultations during development of instructional materials
  • Participation as an ongoing member of team developing the instructional materials
  • Conducting an evaluation of the instructional materials and providing a report
  • Other
Quality of Online/Hybrid Course Design assured by:
  • Custom Quality Rubric
  • Expertise of Project's Instructional Designers
