Megavoltage x-rays are preferred for treatment of deep lying tumours as they are attenuated less than lower energy photons, and will penetrate further, with a lower skin dose. Megavoltage x-rays also have lower relative biological effectiveness than orthovoltage x-rays. Meer weergeven Megavoltage X-rays are produced by linear accelerators ("linacs") operating at voltages in excess of 1000 kV (1 MV) range, and therefore have an energy in the MeV range. The voltage in this case refers to the voltage … Meer weergeven Use of megavoltage x-rays for treatment first became widespread with the use of Cobalt-60 machines in the 1950s.
