Image & Treat Positioning™
The Base of Skull (BoS) headframe is specifically designed to meet the unique requirements of proton therapy for patient immobilization and beam transmission. The BoS™ headframe is engineered to rigidly support the patient without using a flat base that blocks the use of important proton beam angles.
The conformal shape is desired to minimize the distance between the patient and the field defining aperture, optimizing the beam proton penumbra.
