At what location should measurements be made for the Swimmer's View?

The correct choice for where measurements should be made for the Swimmer's View is at the base of the patient's neck. This positioning is crucial because the Swimmer's View is designed to provide a clear radiographic image of the cervicothoracic junction and surrounding structures, particularly when conventional cervical views do not adequately visualize this area due to overlapping shoulder structures.

When making measurements or placing the central ray for this view, it is essential to target the base of the neck because this location serves as a landmark for the C7-T1 intervertebral disc space. Proper alignment at this site helps ensure optimal image quality, reducing the likelihood of distortion or superimposition from the shoulders, which can obscure essential anatomical details.

While other options may reference anatomical landmarks significant in various contexts, they do not specifically focus on the optimal location for capturing the Swimmer's View. For example, shoulder level may not provide a suitable angle for visualization, mid-clavicle alignment differs from the requirements of this specific view, and T1, while a relevant vertebra, is not the proper measurement point for this positioning technique.
