In the early 1990's Dr Stock, working with his urologic collegue Dr Nelson Stone developed a real-time technique
for performing uotrasound guided brachytherapy. Tthis technique relies on real-time transrectal state of the art ultrasound
to guide needle and seed placement. Dr Stock, Dr Stone, as well has Dr Stock's students have taught this
technique to physicians throughout the United States, Europe and Asia. It is the technique most commonly used in Europe,
Africa and Japan. Below is an expert from a review article witten by Dr Stock which describes the technique.

THE DEVELOPMENT OF A REAL-TIME ULTRASOUND-GUIDED IMPLANT TECHNIQUE The advent
of transrectal ultrasound-guided brachytherapy was first reported by Holm and Gammelgaard1 in Denmark in 1981. These investigators
described the use of transrectal ultrasound to help guide needle and seed placement in the treatment of localized prostate
cancer using iodine 125 (125I) radioactive seeds.2 In the last 26 years, there have been many significant advances in low-dose-rate
brachytherapy techniques, all derived from this initial approach.
