Comparative views of Supine Positioning vs. Prone

Figures 1 and 2 – Compare the coverage of the breast tissue and demonstrate the amount of normal tissue that is spared during irradiation.

In Figure 1 – The patient is positioned supine, using a standard breast board. In this position, the chest wall and lung is exposed to the treatment field.

In Figure 2 – The patient is positioned prone, using the Bionix Prone Breast System. In this position, the treatment volume spares the patient’s chest wall and vital organs.
