"C" arm guidance in interstitial brachytherapy of pelvic malignancies.

Since 1979 more than 50 transperineal interstitial implants, both removable and permanent, have been performed at the University of Nebraska Medical Center. The “C” arm of the mobile image-intensifier television unit Siemens Mobile 2 was used to guide the placement of the needles and was found to be useful in achieving accurate implantation.
