The planning of radiotherapy involves a multidisciplinary team of healthcare professionals, including oncologists, radiation therapists, and medical physicists. The process begins with a simulation session, where imaging techniques like CT scans or MRI are used to determine the exact location and size of the tumor. This information is used to create a detailed treatment plan that specifies the radiation dose and the areas to be targeted. During the actual treatment, patients lie on a table while the radiation machine is positioned to deliver the precise dose of radiation. The process is usually painless and takes only a few minutes per session. Treatment schedules can vary but often involve daily sessions over several weeks.
