Sädebased

Sädebased is a term used in the field of radiation therapy to describe a type of radiation beam that is shaped like a fan or a cone. This beam is generated by a linear accelerator and is used to deliver radiation to a specific area of the body. The term "sädebased" is derived from the Finnish word for radiation, "säde," and the English word "based," indicating that the radiation is based or shaped in a specific way.

Sädebased beams are typically used to treat tumors that are located near the surface of the body, such as those in the head and neck region. The beam is shaped to conform to the contours of the body, allowing for more precise targeting of the tumor while minimizing damage to surrounding healthy tissue. This is achieved by using a collimator, which is a device that shapes the beam into the desired shape.

The use of sädebased beams is an important aspect of modern radiation therapy, as it allows for more effective and less invasive treatment of cancer. By using a beam that is shaped to fit the contours of the body, radiation therapists can deliver a higher dose of radiation to the tumor while minimizing the dose to surrounding healthy tissue. This can help to improve the effectiveness of the treatment and reduce the risk of side effects.

In summary, sädebased is a type of radiation beam used in radiation therapy that is shaped like a fan or a cone. It is used to treat tumors near the surface of the body and is shaped to conform to the contours of the body, allowing for more precise targeting of the tumor while minimizing damage to surrounding healthy tissue.
