2 Credits, 2 Contact Hours
2 lecture periods 0 lab periods

Principles of radiographic imaging. Includes program orientation, production of diagnostic radiation, image formation, ethics and professionalism, patient care and assessment, age specific care considerations, and radiographic positioning of the abdomen and chest.

Corequisite(s): RAD 170LB  
Information: Consent of program director is required before enrolling in this course.

Course Learning Outcomes
  1. Define radiologic technologist profession and scope of practice, and define the ethical and legal issues for health care professionals as it relates to age-specific care for infants, children, adults and elderly patients.
  2. Use radiographic positioning terminology and demonstrate proper radiation protection practices, patient assessment, infection control, transfer practices, manipulation, function of x-ray units, and computerized reader systems. 
  3. Define and demonstrate factors that affect image quality and critique images based on Bontrager’s positioning criteria.

Performance Objectives:
  1. Identify the initials which represent the modalities the ARRT certifies.
  2. Distinguish and explain the purpose of: ARRT, ASRT, MRTBE, and ASSRT.
  3. Discuss the ARRT examination procedure by describing the candidate’s general qualifications and educational requirements.
  4. Distinguish between the following specialties and safety concerns found in radiology: CT, MRI, Nuclear Medicine, Ultrasound (Sonography), Radiation Therapy (Oncology), Cardiovascular Interventional Technology, and Mammography.
  5. Discuss the discovery of X-ray.
  6. Identify exposure, non-exposure, overexposure and underexposure on a radiograph.
  7. List the four measures a radiographer can take to protect the patient from excess radiation and improve the quality of the radiograph.
  8. State what the letters ALARA stand for.
  9. Describe the four (4) ways ALARA can be achieved.
  10. Describe and describe the function of each lock on the x-ray tube housing.
  11. Identify the distance indicators: SID = Source-Image Distance.
  12. Maneuver the tube and collimate to the cassettes to a 10 x 12 size and a 14 x 17 size.
  13. Identify and explain the following abbreviations: CR, SID (same as FFD and TFD), KVP, MA, S, and MA.
  14. List the basic components of the x-ray tube.
  15. Describe the components on the control panel.
  16. Define standard terms used in radiographic positioning. 
  17. Describe the name of the four common body types.
  18. Determine the degree of inspiration on chest radiography.
  19. Describe patient preparation for chest radiography.
  20. Identify the various part of the lungs (base, hilum, apex, costophrenic angles) pm a chest radiograph.
  21. Evaluate radiographs of the chest according to Bontrager’s evaluation criteria.
  22. Identify the five topographic landmarks that can be used for positioning the abdomen.
  23. Complete all requirements for clinical admission as stated in the RAD Student Handbook.
