RADT 2100 - Introduction to Computed Tomography

Credits: 1
Hours/Week: Lecture None Lab None
Course Description: This required course includes the fundamentals of computed tomography (CT), equipment components, image creation and manipulation, CT protocols and their applications in radiology and specialized examinations performed in the CT department. Students will have the opportunity to apply the theoretical component in Clinical Radiography III, IV and V, under the direct supervision of a qualified radiologic technologist. This course requires students to be  concurrently enrolled in RADT 2010 , RADT 2090  and RADT 2784 .

Learning Outcomes
At the end of this course students will be able to:

  1. describe the fundamental process of creating a computerized image.
  2. describe the historical perspective of the CT scanner to include generations I-IV, multislice scanners and helical/spiral scanning.
  3. identify the advantages and disadvantages of CT imaging.
  4. list the major components of CT equipment and describe their role in generating a computerized image.
  5. list the steps in acquiring a computerized image.
  6. define the scanning parameters adjusted by the technologist which affects the CT image.
  7. explain image manipulation techniques to include multiplanar reconstruction and retrospective reconstruction.
  8. explain the radiation safety issues that must be followed when operating a CT scanner.
  9. describe the use of contrast medium in computerized tomography to include intravenous, intrathecal, oral and rectal contrast medium.
  10. identify assessment and safety measures for a variety of patients to include pediatrics, trauma and sedated patients.
  11. identify examination protocols for variety of examinations to include:  head/brain, neck, chest, abdomen, spine, and the musculoskeletal system.
  12. describe specialized CT examinations to include: CT angiography, interventional CT, 3D reconstruction, CT fluoroscopy, Virtual Reality Imaging and Positron Emission Tomography (PET) CT.
  13. list the quality assurance and control tests performed on CT equipment.
  14. describe the image artifacts and ways to minimize their appearance on the CT image to include:  beam hardening, partial volume averaging, motion, out of field, and tube arching.
  15. distinguish between the CT appearance of normal organs and tissues from those affected by pathology.
