While nearly half of all patients diagnosed with cancer in the US receive radiation therapy, the majority is delivered via electron accelerators, where photons are used to irradiate cancerous tissue. Because of the physical properties of photon beams, photons may deposit energy along their entire path length through the body. On the other hand, a proton beam directed at a tumor travels in a straight trajectory towards its target, gives off most of its energy at a defined depth called the Bragg peak, and then stops. While photons often deposit more energy within the healthy tissues of the body than within the cancer itself, protons can deposit most of their cancer-killing energy within the area of the tumor. As a result, in the properly selected patients, proton beam therapy has the ability to improve cure rates by increasing the dose delivered to the tumor and simultaneously reduceside-effects by decreasing the dose to surrounding tissue. The benefits of proton beam therapy in delivering a lethal hit to the target while sparing surrounding normal tissues from radiation are becomi | | 出版日期 | Book 2013 | | 关键词 | cancer treatment; cyclotron accelerator; proton beam therapy; radiation therapy; synchrotron accelerator | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4614-5298-0 | | isbn_softcover | 978-1-4899-8671-9 | | isbn_ebook | 978-1-4614-5298-0 | | copyright | Springer Science+Business Media New York 2013 |
