Course Description

Introduces theory and application of inverse square law, distortion, radiographic quality, technique conversion factors, formulation of technique charts, and quality assurance. Includes lab use of energized equipment and test tools.

Addendum to Course Description

The student will develop knowledge and skills in the following areas: geometric aspects, photographic aspects, radiographic image quality,
conversion factors, exposure guides, special modalities and quality assurance.
Principles of Exposure II (RAD 215) is required to graduate from the Radiologic Technology Program. It is also a prerequisite for taking the
American Registry of Radiologic Technologists examination for certification in Radiography. Transferability of credit depends entirely upon the institution to which the student wishes to transfer.

Intended Outcomes for the course

Upon completion of the course the students should be able to:

  • Adapt exposure techniques to obtain high quality images in a clinical setting when patient or equipment factors change.

  • Skillfully apply quality assurance processes when producing images.

Outcome Assessment Strategies

  1. Develop a research paper based on projects listed in "Integrated Mathematics of Radiographic Exposure".
  2. Demonstrate an understanding of quality analysis by providing critique and correction of a reject analysis film.
