Position of tubes (applicators) for brachytherapy - image description

The image shows a woman’s pelvic area and the position of the vagina, cervix and womb. A narrow opening is shown between the legs. This leads into a narrow space shown inside the pelvis. This space is called the vagina. Above the vagina the space narrows until both sides almost touch. Then it opens again to form a hollow, pear-shaped organ called the womb.

At the narrowest area between the vagina and the womb, the lower end of the womb bulges into the top of the vaginal space. The surfaces of the two sides of the bulge are highlighted. This is the cervix.

Three long, thin tubes are shown entering the vagina. The central tube enters the vagina, goes through the cervix and into the womb. The end of this tube sits against the top inner wall of the womb. The two other tubes enter the vagina, one on either side. The ends of these tubes sit between the vaginal wall and the outer edge of the cervix at each side.
