Radiation dose enhancement in skin therapy with nanoparticle addition: A Monte Carlo study on kilovoltage photon and megavoltage electron beams

Figure 1 Schematic diagrams (not-to-scale) showing the experimental setups of the kilovoltage photon beams (left) and megavoltage electron beams (right). The thicknesses of the skin target layer (water mixed with nanoparticles) ranged from 0.5-5 mm for the photon beams and 0.5-10 mm for the electron beams. SSD: Source-to-surface distance.
