Position: Clavicle AP The AP clavicle projection demonstrates the entire clavicle in anatomical position. It evaluates fractures and joint alignment. Proper centering ensures visualization of both AC and SC joints. This projection is essential for trauma imaging. It is a core ARRT requirement.
Position: Clavicle AP Axial The AP axial clavicle projection angles the beam cephalad to project the clavicle above the ribs. This rule reduces superimposition and improves fracture visualization. It is essential for evaluating midshaft injuries. Proper angulation varies with patient habitus. It is a standard ARRT competency.
Position: AC Joints Bilateral AP The bilateral AC joint projection evaluates joint separation and ligament integrity. Images are taken with and without weights. This projection is essential for diagnosing AC joint injuries. Proper positioning ensures symmetry. It is a recognized ARRT exam position.
Position: Scapula AP The AP scapula projection demonstrates the scapular body and acromion. The arm is abducted to move the scapula laterally. This projection evaluates fractures and lesions. It complements the lateral scapula view. It is a standard ARRT competency.
Position: Scapula Lateral The lateral scapula projection demonstrates the scapular body in profile. The patient is rotated to superimpose the scapula. This view evaluates fractures and winging. It is essential for trauma imaging. It is frequently tested on ARRT exams.
Position: Ribs AP Upper The AP upper ribs projection evaluates ribs above the diaphragm. The patient takes a deep inspiration to elevate the ribs. This projection is essential for trauma and pain evaluation. Proper centering ensures visualization of ribs 1 through 10. It is a core ARRT requirement.
Position: Ribs AP Lower The AP lower ribs projection evaluates ribs below the diaphragm. The patient exhales to lower the diaphragm. This projection is essential for evaluating fractures and lesions. It complements the upper rib view. It is a standard ARRT competency.
Position: Ribs Oblique Oblique rib projections rotate the patient 45 degrees to demonstrate axillary ribs. This view improves visualization of rib fractures. Proper rotation depends on the side of interest. It is essential for trauma imaging. It is frequently tested on ARRT exams.
Position: Sternum RAO The RAO sternum projection uses obliquity to project the sternum over the heart shadow. This improves contrast and visibility. A long exposure time blurs ribs and lung markings. This projection is essential for evaluating fractures and lesions. It is a core ARRT competency.
Position: Sternum Lateral The lateral sternum projection demonstrates the sternum free of superimposition. The patient stands sideways with arms behind the back. This view evaluates fractures and deformities. It complements the RAO projection. It is a standard ARRT requirement.
