Newer forms of target tracking have become clinically available. Like the radiopaque fiducial markers used in portal imaging, small radio transponders can be implanted into the prostate for facilitating patient setup. These transponders emit radiofrequency waves that can be detected and used to reposition the target before execution of therapy.
