Radiotherapy Systems, Orthovoltage
Definition : Radiotherapy systems designed to emit x-ray beams produced by electric voltages, typically in the range of 20 to 500 kV. These systems usually include an x-ray source, a manual or automated computerized control unit, filters, collimators, and applicators; some systems also include displays and printer output. Orthovoltage systems, including x-ray tubes operated up to 150 or 200 kV, can perform superficial treatments (e.g., squamous cell carcinoma of the skin, Kaposi's sarcoma), while equipment using tubes with higher voltages (e.g., 300 kV or more) can be used in radiation treatments that reach a few centimeters under the skin.
