Lateral Thoracic Filter (57-407)
Breast Shields (56-409)
To best visualize the thoracic vertebrae, the humeral heads should project anterior to the thoracic spine.
This is done by having the patient place the arms in front of the body, with elbows bent and drawn
together, hands supinated perhaps resting on the IV pole to help stabilize the patient.
Attach the Breast Shields to the Filter holder assembly (magnet- to-steel). Place the Lateral Thoracic
Filter on top of the Breast Shields.
The Lateral Thoracic Filter is placed to project 1" below the axillary border (see Figure 5-11).
Breathing technique is utilized. Measurement is taken posterior to the humeral heads.
When imaging patients with kyphosis: Take measurement through the kyphosis only, to prevent
overexposure.
Collimation 7" x 17".
