Improved precision of interstitial brain tumor irradiation using the brw ct stereotaxic guidance system

Abstract A technique is described which enables precise temporary interstitial volume implantation of brain tumors using a CT Sereotaxic guidance system. This technique has the advantages of designing irregular isodose distributions during the preplanning stage. Although the preplanning stage can be time-consuming, this is performed while the patient is in the hospital room and CT scanner time, anesthesia time, and operating room time is minimized for individual patients.
