Figure 2

View of the experimental set-up of proton irradiation to the phantom with implantable cardioverter defibrillators (ICDs) on the central axis of the proton beam. Four ICDs were placed on the contralateral side of the phantom. Proton beams entered the water phantom laterally, and an acrylic plastic board was set behind the ICDs to provide backscatter conditions. Calculated spread-out Bragg peak (SOBP) curves in water and experimental values are included.
