Varian Medical Systems received U.S. and European approvals and is now launching its new Calypso 17G soft tissue Beacon transponder. The device which allows for real time tracking of soft tissue tumors is now half the size of the previous model. This should help improve applicability of the technology for smaller tumors while increasing the accuracy of radiation treatments.
The beacon emits non-ionizing radio signals that are picked up by the Calypso system and triangulated accurately to the position of the tumor. Once located, the radiation beam can then be aimed at and around the beacon’s location, guaranteeing that the tumor tissue, even if moved after imaging, will be in the radiation beam’s sights.
