three-dimensional conformal radiation therapy (3D-CRT)

A type of external radiation therapy that uses a computer to shape the radiation beams to the shape of the tumour. This delivers high doses of radiation to the tumour while sparing the normal tissues as much as possible. Beams…

radiation therapy

The use of radiation, usually x-rays or gamma rays, to kill cancer cells or injure them so they cannot grow and multiply. Sometimes radiation therapy is used to control pain.

intensity modulated radiation therapy (IMRT)

A type of external radiation therapy in which the radiation beams are aimed from several directions, while the intensity (strength) is controlled by computers. This helps to reduce some side effects.

selective internal radiation therapy

News: State-of-the-Art Radiation Therapy Starts up at Springfield

Springfield’s first radiotherapy service opened its doors this week, enabling local cancer patients to access more affordable, timely treatment. The first patient received radiation therapy earlier this week at the new Radiation Oncology Centres (ROC) facility, based at the new…

internal radiation therapy

See brachytherapy or radioisotope therapy.

external beam radiation therapy

The use of high-energy radioactive beams to kill cancer cells or injure them so they cannot multiply. The beams of radiation are directed at the cancer from a machine.

volumetric modulated arc therapy (VMAT)

A type of radiation therapy whereby single or multiple beams of radiation sweep around the body, greatly reducing treatment time….

radiation

Energy in the form of waves or particles, including gamma rays, x-rays and ultraviolet (UV) rays. This energy is harmful to cells and is used in radiation therapy to destroy cancer cells.
