Radiation therapy linac. Intraoperative radiation therapy iort and linear acceleraor linac using remedis proprietary miniature x ray tube the iort targets skin cancer and breast cancer treatment for breast conserving surgery. Treatment sessions may vary in complexity and time. The linac is used to treat all body sites using conventional techniques intensity modulated radiation therapy imrt volumetric modulated arc therapy vmat image guided radiation therapy igrt stereotactic radiosurgery srs and stereotactic body radio therapy sbrt.

The elekta unity mr linac a high field 15 tesla mr guided linear accelerator is the worlds first radiation therapy technology to combine an mri scanner with a linear accelerator in a single system. Dana farberbrigham and womens cancer center is the first cancer center in new england to offer this cutting edge radiation treatment on an mri linac. In some patients they can be severe.

They can fine tune the radiation treatment plan and personalize and adapt each treatment in ways they never could before. A short while later in 1954 a 6 mv linac was installed in stanford usa which began treatments in 1956. The rt machine uses a high energy linear accelerator linac as the source of the ionizing radiations which can be high energy electron beams or x rays photon beams of an x ray linear accelerator.

While the underlying principle of a linac is remarkably simple implementation of that principle to produce a consistent stable beam requires a precise and sophisticated design. Modern machines better focus the radiation and do less damage to normal tissues so doctors can use higher doses of radiation. Radiation treatments may cause side effects that can vary depending on the part of the body being treated.

Linac based radiation therapy for cancer treatment began with the first patient treated in 1953 in london uk at the hammersmith hospital with an 8 mv machine built by metropolitan vickers and installed in 1952 as the first dedicated medical linac. About 10000 are in use all over the. The machine most commonly used is called a linear accelerator or linac radiation technology allows the precise delivery of external beam radiation therapy.

In radiation therapy the majority of radiation treatments use x rays and a smaller number uses the electron beam or a combination of both therapies. The art has been refined and improved in both design and materials. The medical linear accelerator linac is the primary workhorse for radiation oncology.

Radiation therapy is not appropriate for all patients.
