Course Number and Title: VET 235 Diagnostic Imaging
This course provides theoretical and practical information needed to produce diagnostic radiographs on a wide variety of species, including dogs, cats, horses and exotics. Other topics include patient/staff safety, ultrasonography, contrast studies, and digital radiography. Clinical sessions provide the student hands-on experience with concepts learned during lecture.
Students are provided dosimetry badges.
Student must have completed required rabies pre-exposure vaccination series or document proof of protective titer before taking this course. The cost of the series is the responsibility of the student and may not be covered by insurance.
- Describe the basic applications of medical radiology, including information provided by a diagnostic radiograph, production of x-rays by an x-ray machine, production of radiographs with cassette-screen film, and both automatic and manual film processing. (CCC 2, 6; PGC 2)
- Produce diagnostic quality radiographs on a variety of species using proper equipment, restraint, positioning, and technique. (CCC 2, 6; PGC 2)
- Describe other diagnostic imaging techniques used in veterinary medicine. (CCC 2, 3; PGC 1)
- Implement and follow recommended radiologic safety measures. (CCC 2, 3, 6: PGC 1, 2)
- Adhere to the professional behavior and ethical conduct as outlined in the Veterinary Technician Code of Ethics. (CCC 1, 3, 4; PGC 3)
See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.
