[Shielded vaginal applicators for line-shaped 192Ir sources for use in the irradiation of cervix cancer].
The possibility is investigated to use shielded vaginal applicators for "line-shaped" 192Ir-sources to irradiate cervical carcinoma. Using segment-shaped absorbers of heavy metal the dose can be reduced in ventro-dorsal direction in area of rectum and bladder with irradiation of cervical carcinoma up to a factor of 2 in dependence of rectum and bladder position. Selecting a suitable source position and source standing time a dose reduction can be realized in cranial direction up to two centimetres from the portio.
