Fig. 4.1 Bird’s-eye view of the HIMAC facility The HIMAC facility has employed a single beam-wobbling method, which is one of the passive beam delivery methods [10], as shown in…

Quantities for 60Co in the in the denominator of the above equation are well established. For protons, there are some uncertainties. According IAEA TRS 398, Wair/e for protons is 34.23 ± 0.14…

Fig. 5.1 Physical selectivity vs. linear energy transfer (LET) (radiobiological advantage) and cost for different types of beams and techniques (Modified from Raju [2]) While protons are at present rapidly…

Fig. 7.1 Effect of pencil beam size on the dose distribution. Dose volume histograms (DVH) for the target volume (prostate) and the rectum obtained with different pencil beam size and…

Fig. 3.1 Basic modular design of particle therapy systems The beam production system is the “engine” of the particle therapy system. It is responsible for the acceleration of particles to…

(9.1)where K = 0.307075 MeV cm2 g−1, z is the charge of the projectile ion, Z/A is the average ratio of the atomic number over the atomic mass of the medium, W…
