The Calypso Localization System and Cybermark Fiducial System are treatment tools that help our doctors deliver focused doses of radiation with greater accuracy to prostate cancer patients that are receiving external beam radiation therapy.

Three tiny transponder “seeds,” each the size of a grain of rice, are placed inside the prostate. These seeds enable the radiation therapist to visualize and more precisely target where the prostate is located and ensure that the radiation is focused on the tumor site.
