Intensity-modulated proton therapy is effective for complex targets Proton beam therapy (PBT), with its characteristic Bragg peak, holds the promise of further reducing toxicity. Several techniques exist for the administration…
Introduction Numerous planning studies demonstrate superior dosimetry for proton radiotherapy compared with photon-based radiotherapy for breast cancers of all stages, even compared with intensity-modulated radiotherapy. Protons can reduce dose to…
Introduction Proton beam radiation (PBR) has the potential to improve the therapeutic ratio in the treatment of several gastrointestinal malignancies by decreasing the dose to nontarget critical structures. In general,…
Introduction For both primary and metastatic brain tumors, radiation therapy (RT) remains one of the standard treatment modalities. Although RT techniques using photons have greatly improved in recent decades, substantial…
Introduction In radiation oncology, “clinical commissioning,” or simply “commissioning,” refers to the process that takes place after a machine has passed acceptance tests but before the first patient can be…
Introduction Intensity-modulated proton therapy (IMPT) can begin only after a number of other processes have been completed, including simulation and treatment planning. For both proton and photon treatments, radiation oncology…
Introduction Intensity-modulated proton therapy (IMPT) using pencil beam scanning (PBS) technology is advancing rapidly for delivering precise and more conformal doses to target volumes while sparing surrounding normal and critical…
Introduction The potential of physical characteristics of protons for cancer treatments was first recognized by Wilson in 1946. During the following four decades or so, proton accelerators at various physics…
Introduction Radiotherapy is used as one of the major treatment modalities for patients with malignant diseases at different disease stages. Currently, the most common radiation choice for the majority of…
10 Foreign Bodies Tim B. Hunter and Mihra S. Taljanovic Introduction Foreign bodies are uncommon, but they are important and interesting. Sometimes, they may provide a great deal of low-brow…
