  • Articulate the principles and fundamentals for various forms of x-ray production and image formation such as, ultrasonography, CT, Endoscopy and MRI
  • Position companion animals and equine patients for routine radiography studies
  • Generate x-rays of companion animals using the x-ray apparatus while implementing safety measures
  • Recognize and evaluate technical errors and artifacts, their causes and prevention, on a radiograph
  • Formulate radiographic technique charts for equipment
  • Perform regular care, storage and maintenance of radiographic equipment and accessories
  • Discuss legal ownership of radiographs and their proper handling regarding client privacy
