The marker should be placed on the cranial aspect of the foot. The patient is positioned in lateral recumbency with the affected limb closest to the plate or cassette. The field of view can be collimated to include only the mandible from the tip of the jaw to the ear or to include the entire skull, depending on the clinicians preference (FIGURE 21). Tape around the proximal phalanges and extend the forelimb cranially. The patient is positioned in sternal recumbency with a triangular wedge under the abdomen and pelvis. Essential equipment includes foam wedges of various shapes and angles, sandbags, cotton ties, radiolucent fibreglass troughs and adhesive tape. We work with veterinarians, veterinary students, and other scientists to provide consultation, education and innovative research. (VSPN Review). The book begins with a very good overview of the principles of radiographic positioning which includes patient preparation, directional terminology, positioning aids, as well as proper collimation, measurement, and labeling requirements. The marker should be placed on the cranial aspect of the foot. Study Details: For this view, the patient's 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).This view needs to be collimated down to just include the top of the head (FIGURE 9). July 2009. The tube head will need to be angled about 20 to direct the beam inside the mouth (FIGURE 15). For example, the ball in the marker shown in FIGURE 1 is 25 mm in diameter. The patient is positioned in dorsal recumbency. The tube head is angled for this view but is aimed dorsoventrally. AST Standards of Practice for Ionizing Radiation Exposure in the Perioperative Setting. We will continue this discussion in part 2. Radiographs themselves are painless and noninvasive, but unsedated restraint can make the patient anxious, scared, and sometimes aggressive.2 This not only harms the patient, but also makes it more difficult to obtain diagnostic results in an efficient manner and can endanger team members. For sedated patients, a large foam pad can be used to elevate and rest the head and extend it away from the forelimb of interest. 2. The marker should be placed on one side of the patient to indicate right or left. Use some cotton or a radiolucent wedge under the tarsus to aid in superimposing the femoral condyles (FIGURE 16). A V trough or other positioning device should be used to ensure the patient is as straight as possible (FIGURE 27). 3. 1.

She stays busy these days by spending the evenings with her family on their small farm in Attica, Ind. Cotton or a foam wedge may be used under the carpus or elbow to enable a true lateral position through the radiohumeral joint space. Pull the affected limb cranially and position it in a normal walking motion, using tape or a sandbag to secure it in place (FIGURE 22). For this view, it is necessary to include the entire tibia, from the stifle to the tarsus, to calculate the slope of the tibial plateau. The terms used to describe radiographic positioning can be confusing and depend on the area being imaged. The marker should be placed on one side of the patient to indicate right or left. During the visual inspection, all ties, buckles, and Velcro straps should be checked to ensure they are in working condition. The marker should be placed on one side of the patient to indicate right or left. The maxilla should be centered on the plate or cassette, and the field of view should include the rostral maxilla to the pharynx region or to C2 (FIGURE 16). The series consists of 2 views: mediolateral and caudocranial. Welfare of the patient. If the elbows are rotated, tape around them and pull in either direction to ensure that they point straight up. Markers should always be placed to indicate patient position and/or beam direction. The exact level of radiation exposure that causes cell death is not known, so all exposure should be treated as if it is going to produce cell death. ; More than 1,000 full-color photos and updated radiographic images visually demonstrate the relationship between anatomy and positioning. The reference line for this calculation is the mechanical axis of the tibia, which is defined by drawing a line through the talus and the intercondylar spines, then identifying the cranial and caudal edges of the medial part of the tibial plateau. The patient is positioned in lateral recumbency with the affected limb closest to the plate or cassette. The skeletal system and joints.

Center the beam over the elbow (FIGURE 38) and collimate to include half of the humerus and half of the radius and ulna (FIGURE 39). The view must include the entire head from the base of the skull to the tip of the nose (FIGURE 5). The terms used to describe radiographic positioning can be confusing and depend on the area being imaged. Three types of restraint are used for avian and exotic patients during radiography: (1) manual, (2) physical, and (3) chemical. It is suggested (but unfortunately not required) that all personnel working with radiation-emitting devices wear a 0.25- to 0.50-mm lead apron or wrap, lead thyroid shield, lead gloves, and even lead-lined goggles.6 These guidelines can vary by state, but most states have adopted the minimum of 0.25-mm lead equivalent.7,8. If the patient is under heavy sedation or general anesthesia, it may be placed in lateral recumbency with the affected dental arcade closest to the plate or cassette.
