Course Description

Covers the practical application of radiography in the veterinary profession. Includes principles of x-ray production, the operation and uses of x-ray machines, the care and development of films, and radiographic positioning of animals.

Addendum to Course Description

The purpose of this course is to introduce students to the field of veterinary radiography.  Whereas radiography is the science of exposing and processing of x-ray films, radiology involves radiography plus the reading and diagnostic interpretation of radiographs, which by law is the domain of the licensed veterinarian.  Therefore this course is solely devoted to teaching radiography.   

The course is designed for second-year veterinary technology program students and is a graduation requirement for the Associates Degree in Applied Sciences in Veterinary Technology.  Credits in this course are not transferable to a four-year school towards a baccalaureate degree.  

The required textbook is Radiography in Veterinary Technology by Lavin. 

Intended Outcomes for the course

Upon successful completion of the course, the student will be able to:

Safely and effectively produce diagnostic radiographic images.

Properly (1) prepare radiographic and darkroom equipment, (2) measure and position animals using topographic landmarks, (3) choose an appropriate radiographic technique to minimize the need for repeat exposures (4) produce the latent image, (5) process the exposed film, (6) analyze the final radiograph for quality in order to provide maximum diagnostic benefit.

Use an understanding of diagnostic quality images to determine options to correct deficiencies and to maximize diagnostic benefit and minimize radiation exposure based on repeated images.

Apply knowledge of the health risks and effective safety procedures and professional judgment to minimize risks to personnel and patients during radiographic procedures.

Properly prepare the imaging site and equipment and position patients appropriately for the non-radiographic study being conducted (ultrasaound).

Course Activities and Design

This course is designed to be a lecture and laboratory course.  It is a three credit-hour course that meets for two lecture hours per week and three lab hours per week.  There are two three-hour lab sections taught in order to accommodate the number of students in the class.  Each section is limited to 15 students per lab section.  

Lecture topics covered are a review of radiation safety principles, the x-ray machine and parts, x-ray production, imaging, processing, positioning, interpretation of diagnostic quality, contrast studies, and the basics of ultrasonography.  In the laboratory students acquire hands-on experience in patient positioning and imaging techniques, creation of a technique chart, and assessment of radiographic diagnostic quality.  

Students will be divided into smaller working groups in lab.  Each group of students will submit a laboratory project to be graded. It will consist of their technique charts, the best radiographs produced during each laboratory session, and their evaluation of radiographic quality.

Outcome Assessment Strategies

  • Grading will be based upon student understanding of the course content as demonstrated by periodic examinations, homework assignments, quizzes, a comprehensive final exam, performance of laboratory tasks, and attendance. To be eligible for a passing grade, the student must have attended a minimum of 80 percent of each of the lecture and lab classes
  • Graduate performance on the “Radiography” sub-section of the Veterinary Technicians National Examination
  • These outcomes will be routinely assessed and used to drive relevant changes in the curriculum.
