Production and Properties of Radiationadiation. Particles are directly ionizing while electromagnetic radiation is indirectly ionizing because it sets other particles in motion to deposit the dose. The majority of innovation in radiation therapy has focused on electromagnetic radiation, beginning with X-ray tubes and γ-rays emitted from

Interactions of Particulate Radiation with Matterrpose of describing particle radiotherapy. Particles can be described as charged or uncharged and heavy or light. Charged particles are usually directly ionizing by acting through coulombic forces while uncharged particles are indirectly ionizing, often causing ionization as a secondary consequence

Dosimetry of Photon Beams in Waterapter provide several methods for calculating monitor units, depending on treatment setup variables such as source-to-surface (skin) distance/source-to-axis distance (SSD/SAD), field size, depth, wedges, and other factors. SSD setups are calculated using percent depth dose (PDD)-based formulae, whil

Dosimetry of Photon Beams in a Patientions in shape and density. These dose correction techniques range from very simple rules to complex computer algorithms. Wedges and compensators may be used to correct for patient surface shape. Bolus may be used to increase the surface dose. Field-matching techniques may be used for treatments with

Dosimetry of Electron Beamsons. Surface dose increases with energy, unlike photons. Simple dose calculations are based on electron dose to water, using source-to-surface distance (SSD) setup geometry. Density inhomogeneities greatly alter electron dose distributions. Electrons take the path of least resistance, increasing the
