　　Objective To pinpoint the tracking movement of normal acromioclavicular(AC)joint using volume scan on sensation 320 CT(Aquilion One,Toshiba).Method Data of dynamic scans of 21 shoulders was collected using the motor function of 320 CT and prospectively analyzed.The data of movement of the AC joint was obtained during shoulder forward flexion(from 0°-180°)by 320 CT from all volunteers.The 3D coordinate of moving AC joint was recorded by each 30 ° during shoulder flexion(0u,30r,60r,90r,120i,150i,180°)to investigate the dispose relation of the essential anatomical bony structures of the AC joint(acromion,clavicle,coracoid,head of humerus and glenoid cavity),thus pinpointing the tracking movement of normal AC joint.
