What is 139: In-Vivo Comparison of an Electromagnetic System to Standard kV X-Rays for Treatment Setup During External Beam Radiotherapy of Patients With Prostate Cancer about?
Purpose/Objective(s): The Calypso ® 4D Localization System ("Calypso System", Seattle, WA) utilizes implanted Beacon® transponders and electromagnetic technology to localize a radiation target prior to and during radiation therapy delivery. A multi-institutional FDA-approved clinical study was conducted to evaluate the utility of this emerging technology for localizing the prostate in relation to machine isocenter during patient set-up. One of the aims of the study was to compare precision of the AC electromagnetic device to a commercially available stereoscopic kV x-ray system (BrainLab ExacTrac) incorporated with the linear accelerator for image-guided radiotherapy. This report summarizes the result of this clinical study. Materials/Methods: Forty-one (41) patients at five institutions were enrolled in the study. Each patient underwent implantation of three resonant circuit transponders (Beacon ® transponders) within prostate about two weeks prior to CT simulation. At the time of treatment set-up, the Calypso System's array, containing electromagnetic circuits, was placed anterior to patient's pelvis to energize and detect the transponders, which in turn computed the exact locati
