Background:
Currently used positioning landmarks for the lateral scapula and Y projections often yield inconsistent results and lead to repeats.
Objective:
To determine whether new positioning landmarks can help radiographers position the lateral scapula and Y projections more accurately.
Methods:
Following laboratory experimentation on dry bone specimens, a small pilot study was conducted in the clinical setting to test the new landmarks.
Results:
Laboratory and clinical testing of the use of the acromial tip and superior angle of the scapula suggest that these landmarks are easier to use and improve accuracy of positioning.

Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
