I was very pleased with the number of views (including some less common views) covered in this text, as well as the comprehensive number of photographs and diagrams included. This view requires the maxilla to be parallel to the table, so it is best to secure the maxilla with tape across the hard palate. Providing the most information we can to obtain the best possible diagnosis or outcome for the patient is our primary goal! For this view, the patients nose should be perpendicular to the plate or cassette, so the nose should be pointing up at a 90 angle from the table and wrapped with tape to secure it in this position (FIGURE 8). The patient is positioned in sternal recumbency. PPE is expensive; therefore, it requires appropriate handling and maintenance. One of the standards we follow at Purdue is to perform a complete radiographic series, no matter what is being imaged. The following tutorial includes positioning instructions to obtain two orthogonal views for the skull, shoulders, and elbows. Therefore, start by placing 1 to 2 inches of padding under the patients pelvis to aid in rolling the stifle down toward the table to be parallel with the table (FIGURE 2). Lateral view of the skull with details of the teeth. Using this marker allows the veterinary team to adjust for magnification by calibrating the radiograph with a known value: the size of the metal ball at the end of the flexible arm. Collimate over the pelvis to include the wings of the ilium and the ischium. Anthony Douglas Williams, spiritual author, once said, When I look into the eyes of an animal, I do not see an animal.
