Student Learning Outcomes

  • Demonstrate proper equipment manipulation and assist in the performance of computed tomography procedures, applying appropriate patient care and radiation protection principles in the clinical setting.
  • Critique and distinguish relevant sectional anatomy and pathology related to computed tomography.

Description

This course focuses on patient care, safety, image production and procedures related to computed tomography as well as clinical practicum in a computed tomography department. Practical experience is implemented to expose the post-graduate radiologic technology student to the principles of CT with emphasis on mastery of the knowledge, insight and skills required to perform CT procedures.

Course Objectives

The student will be able to:

  1. Review patient history to identify contraindications prior to the examination.
  2. Perform venipuncture in the upper extremity for the purpose of injecting contrast media.
  3. Relate how radiation interacts with human tissues for the purpose of radiation protection.
  4. Maintain radiation protection for the patient, personnel, and self.
  5. Exhibit knowledge and understanding in the proper use of the CT equipment.
  6. Explain acquisition parameters and data reconstruction as it relates to CT image processing.
  7. Critique and evaluate CT images for good diagnostic quality.
  8. Select proper scanning parameters and patient positioning as outlined by the department protocols.
