Method and apparatus of the irradiation of new-onset linked at the age

摘要

The procedure, designed for the treatment of subretinal vessels produced by age-related macular degeneracy, consists of focusing gamma radiation from a radioactive source (1) through a cylindrical collimator (3) with fixed stages of small diameter and directing the beam onto the macular zone with the aid of an adjustable target and a movable armchair (4) on rails (10). The radioactive source, such as Cobalt 60 or Caesium 137, is held in a container (2) which ensures the radio-protection of personnel and is made from a metal selected from lead, tungsten or depleted uranium 235.
