Course DescriptionTeaches 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. Prerequisites: VT 105, 106, 109.
Addendum to Course DescriptionThe purpose of this course is to introduce the student to the field of veterinary radiography. Whereas radiography is the science of taking and processing of x-ray films, radiology involves radiography plus the reading and interpretation of radiographs, which by law is the domain of the licensed veterinarian. Therefore this course is solely devoted to teaching radiography.
This is designed for second year veterinary technology 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 text for this course is Radiography in Veterinary Technology by Lavin.
Intended Outcomes for the courseUpon successful completion of the course, the short term outcome will be that the student will have satisfactorily accomplished the goals and objectives of this course content guide and confirmed as provided in the assessment above. The long-term outcome desired is for the student to gain sufficient skills and knowledge of veterinary radiography and ultrasound to successfully pass the National Veterinary Technician Board Examination and effectively utilize the knowledge gained in their Cooperative Education Experience and as a practicing veterinary technician upon graduation. The course content guides are developed by college-wide subject area faculty and approved by the administration.
Laboratory tasks with an asterisk indicate tasks the student must be able to perform since they are listed as essential tasks, and tasks with two (**) asterisks indicate tasks considered to be recommended tasks by the Accreditation Policies and Procedures of the Committee on Veterinary Technician Education and Activities of the American Veterinary Medical Association. Tasks with no asterisks are considered neither essential nor recommended, but are taught based on instructor, SAC, and/or advisory committee recommendations. This course content and outcome guide specifies which tasks students are required to perform (as indicated in the task description) and the tasks on which they have been educated and have observed but individual performance is not required.
The goal is for the student to develop knowledge and about the field of radiography.

The goal is for the student to develop a working knowledge of the principles and diagnostic use of ultrasonography.
17.0 OTHER IMAGING AND TREATMENT MODALITIES
The goal is for the student to learn about methods employed to treat lesions utilizing radiation, and using other imaging techniques
Course Activities and DesignThis 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 12 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 basics of ultrasonography. In lab the student practices positioning, imaging techniques, learns how to make a technique chart, and assesses radiographic diagnostic quality.
Each group of students in lab will turn in a laboratory project to be graded. It will consist of their technique charts, the best radiographs taken each lab, and their evaluation of their radiographs.
