Linac Radiation Therapy

Modern machines better focus the radiation and do less damage to normal tissues so doctors can use higher doses of radiation. 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.

The machine most commonly used is called a linear accelerator or linac radiation technology allows the precise delivery of external beam radiation therapy.

Linac radiation therapy. 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. In addition to treating cancer radiation oncologists may also use ionizing radiation to treat benign tumors that are unable to be removed by surgery. 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 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. A short while later in 1954 a 6 mv linac was installed in stanford usa which began treatments in 1956. Radiation therapy the use of ionizing radiation high energy radiation that displaces electrons from atoms and molecules to destroy cancer cells.

In some patients they can be severe. Radiation therapy is not appropriate for all patients. Treatment sessions may vary in complexity and time.

The maps unit includes a high field strength 30t magnet for diagnostic quality imaging for initial radiation therapy planning. The mri linac meanwhile is a state of the art hybrid device that integrates a modified lower field 035t mri scanner with a linear accelerator radiation delivery machine to reduce the magnetic interference on. 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.

Radiation treatments may cause side effects that can vary depending on the part of the body being treated. Remedis radiation therapy offers two distinctive solution.
