| external radiation therapy | Radiation therapy using a machine located outside the body to aim high-energy rays at a tumour. (12 Dec 1998) |
| radium beam therapy | Therapeutic use of radium rays, the source of which is a quantity of radium at a distance from the patient. Synonym: radium beam therapy. (05 Mar 2000) |
| external radiation | Radiation therapy that uses a machine located outside the body to aim high-energy rays at the cancer. (16 Dec 1997) |
| radiation therapy | <radiobiology> Treatment with high energy radiation from X-rays or other sources of radiation. (16 Dec 1997) |
| photodynamic radiation therapy | <oncology, technique> A light sensitive drug is given through a vein and concentrates in the tumour. Then, during a surgical procedure, a special light activates the drug. The activated drug kills tumour cells. (31 Dec 1997) |
| internal radiation therapy | Radiation therapy in which radioactive material is placed in or near a tumour. (12 Dec 1998) |
| interstitial radiation therapy | <oncology> The implantation of radioactive seeds directly into a tumour. (10 Jan 1998) |
| intraoperative radiation therapy | Treating a tumour site withradiation immediately following surgery to destroy the tumour. (09 Oct 1997) |
| advanced multiple-beam equalization radiography | A variant of scanning equalization radiography using several X-ray beams. (05 Mar 2000) |
| Balkan beam | An overhead frame, supported on uprights attached to the bedposts or to a separate stand, from which a splinted limb is slung in the treatment of fracture or joint disease. Synonym: Balkan beam, Balkan splint. (05 Mar 2000) |
| beam | <radiobiology> Stream of particles or electromagnetic radiation travelling in a single direction. (09 Oct 1997) |
| beam dump | <radiobiology> A mass of shielding material which absorbs the energy of a beam of particles or electromagnetic radiation. (09 Oct 1997) |
| beam-plasma reaction | <radiobiology> Fusion reaction which occurs from the collision of a fast beam ion with a thermal plasma ion. (09 Oct 1997) |
| beam splitter | <radiobiology> Optical device for dividing a beam of electromagnetic radiation into two or more separate beams. (09 Oct 1997) |
