Doctor reviewing a radiation treatment plan. In radiotherapy, radiation treatment planning (RTP) is the process in which a team consisting of radiation oncologists, radiation therapist, medical physicists and medical dosimetrists plan the appropriate external beam radiotherapy or internal brachytherapy treatment technique for a patient with cancer.
In modern radiation therapy, 3D dose distributions are typically created in a computerized treatment planning system (TPS) based on a 3D reconstruction of a CT scan. The "volume" referred to in DVH analysis is a target of radiation treatment, a healthy organ nearby a target, or an arbitrary structure.
Radiation therapy (RT) is in itself painless, but has iatrogenic side effect risks. Many low-dose palliative treatments (for example, radiation therapy to bony metastases) cause minimal or no side effects, although short-term pain flare-up can be experienced in the days following treatment due to oedema compressing nerves in the treated area ...
RaySearch Laboratories (AB publ) is a Swedish medical technology company that develops software used in radiation therapy of cancer. The company markets its products worldwide and has subsidiaries in the United States, Singapore, Belgium, France, Germany, and the United Kingdom. RaySearch markets the RayStation treatment planning system.
Radiation oncologists directly enter radiation oncology residencies of 5 years duration, with the first year as an internship year. During the next four years, residents complete intensive training in clinical oncology, in radiophysics and radiobiology, and in the treatment planning and delivery of radiotherapy. [2]
Most radiation therapy is planned using the results of a 3D CT scan. A 3D scan largely presents a snapshot of the body at a particular point in time, however due to the time of the acquisition, in which the patient is likely to have moved in some way (even if only breathing), there will be an element of blurring or averaging in the 3D scan. [ 6 ]
Conventional radiation techniques such as external beam radiotherapy (EBRT) following surgical removal of the tumor have several drawbacks: The tumor bed where the highest dose should be applied is frequently missed due to the complex localization of the wound cavity even when modern radiotherapy planning is used.
SGRT can help to improve the safety, effectiveness and efficiency of radiation therapy treatments, by offering guidance across every step of the radiation therapy workflow, including simulation, planning, treatment and dose visualisation.
