Critique PACEMAN	Positioning The patient was positioned with no rotation of the shoulders, evidenced by The sternal/medial end of the clavicle is seen adjacent to the lateral edge of the vertebral column Sufficient cephalic angle is used, evidenced by From the middle to the lateral aspect of the clavicle is projected above the scapula and acromion process The medial end of the clavicle is seen to super-impose the upper first to third ribs The clavicle may appear to have a slightly upward bow Area Covered Entire clavicle, acromioclavicular joint, sternoclavicular joint, acromion process Collimation Centre: Palpate the ends of the clavicle and centre midwat between (mid-clavicle) Shutter A: Open to include jugular notch and beyond the acromioclavicular joint Shutter B: Open to include the superior and inferior aspects of the clavicle Exposure Bony trabeculation and sharply defined cortical outlines of the clavicle The distal clavicle and acromioclavicular joint are seen with appropriate density The medial end of the clavicle and the sternoclavicular joint are visualised through the thorax Soft tissues are visualised
