Modified ovoid applicator for intracavitary radiation therapy with a Selectron-MDR or microSelectron-HDR.
A modified ovoid applicator for intracavitary radiotherapy was developed for Japanese and other Asian women. It has more variations of smaller sized ovoids than the original rigid standard applicator of the Selectron-MDR and microSelectron-HDR. In addition, application of the ovoid pair and tandem flange is easy due to the flat surface of the inner aspect of the ovoid pairs, which prevents slippage of the ovoids and flange. The applicator is described together with source loading and dose distribution.
