Purpose: The high dose region of a pristine proton beam Bragg peak is only 4-5 mm in width. To be clinically useful, this peak must be modulated into a "Spread Out Bragg Peak" (SOBP). This range modulation can be achieved in a number of ways. At the Midwest Proton Radiotherapy Institute –[for full text, please go to the a.m. URL]
