Dose Calculations for Radiation Treatment Planning
The most common method of treating cancer patients with radiation is externally applied beams of photons generated by linear accelerators, or by high-intensity 60Co radioactive sources. Electron beams generated by linear accelerators also are employed, but not as often as photon beams. Other particles, such as protons, neutrons, pions and heavy ions, have been experimented with, but their use is limited to a few research facilities. For certain types of tumors, internally applied radiation, alone or in combination with external radiation, is suitable. In this chapter, we will confine ourselves to externally applied photon and electron beams only.
