Position: AP Ankle The AP ankle projection demonstrates the distal tibia, fibula, and talus. Proper dorsiflexion prevents foreshortening. This projection evaluates fractures and joint alignment. It complements mortise and lateral views. It is a core ARRT competency.
Position: Mortise Ankle The mortise ankle projection rotates the leg 15 to 20 degrees to open the ankle joint. It evaluates ligament injuries and fractures. Proper rotation ensures equal joint space. This projection complements AP and lateral views. It is frequently tested on ARRT exams.
Position: Lateral Ankle The lateral ankle projection demonstrates the talus, calcaneus, and distal tibia. It evaluates fractures and soft tissue swelling. Proper positioning prevents rotation. This projection complements AP and mortise views. It is a standard ARRT requirement.
Position: AP Foot The AP foot projection demonstrates the metatarsals and phalanges. A slight angle opens joint spaces. This projection evaluates fractures and deformities. Proper centering ensures full coverage. It is a core ARRT competency.
Position: Oblique Foot The oblique foot projection rotates the foot 30 to 45 degrees to separate the metatarsals. It evaluates fractures and joint alignment. Proper rotation prevents distortion. This projection complements AP and lateral views. It is frequently tested on ARRT exams.
Position: Lateral Foot The lateral foot projection demonstrates the foot in profile. It evaluates fractures, soft tissue swelling, and arch alignment. Proper positioning prevents rotation. This projection complements AP and oblique views. It is a standard ARRT requirement.
Position: AP Axial SI Joints The AP axial SI joint projection uses a cephalic angle to open the joint spaces. It evaluates degenerative changes and inflammation. Proper centering ensures diagnostic quality. This projection complements oblique SI views. It is recognized on ARRT exams.
Position: Axial Calcaneus The axial calcaneus projection demonstrates the calcaneus and subtalar joint. Proper dorsiflexion is essential. This projection evaluates fractures and heel spurs. It complements lateral calcaneus views. It is frequently tested on ARRT exams.
Position: AP Hip The AP hip projection demonstrates the proximal femur and acetabulum. Internal rotation reduces anteversion. This projection evaluates fractures and joint pathology. Proper centering ensures diagnostic quality. It is a core ARRT requirement.
Position: Lateral Calcaneus The lateral calcaneus projection demonstrates the calcaneus in profile. It evaluates fractures and joint alignment. Proper positioning prevents rotation. This projection complements axial views. It is a core ARRT competency.
