Taylor 741 solutions Where should the center of the IR be positioned for a lateral projection of the shoulder?Shoulder Girdle/Clavicle. What type of CR angle is required for the PA Transaxillary projection?PA transaxillary (Hobbs modification) requires a 5° to 15° CR cephalic angle.
What is the central ray angle for the PA oblique projection of the shoulder joint?Central ray: The central ray should be 5-15 degrees laterally traversing the shoulder joint and toward the area of the elbow.
When performing the AP projection of the shoulder where is the CR directed?In the Alexander method (AP axial projection), which is superior in delineating abnormalities of AC joint, the CR is directed to the coracoid process at a cephalic angle of 15°. This angulation projects the AC joint above the acromion.
