Summary

Small Animal Radiographic Techniques and Positioning is a practical, clinically applicable manual designed to aid veterinary technicians and nurses in recognizing and correcting common artifacts in both film and digital radiography, as well as positioning the small animal patient for clear and consistent radiographs. Detailed positioning techniques are provided for each commonly radiographed body segment of small animal patients, including positioning aids, alternative restraint methods, and examples of the corresponding correct or incorrect radiographs. Species covered include dogs, cats, birds, and common exotics. This user-friendly manual also discusses the technical factors associated with digital imaging, radiation safety, and how to construct and use technique charts. A companion website also provides all positioning photographs and radiographs electronically for quick reference. Highly illustrated, Small Animal Radiographic Techniques and Positioning is a must-have resource for any veterinary technician or student working with digital imaging or looking to improve the clarity of small animal radiographs .
