Stereotaxis, a method of localizing a specific point using three dimensional coordinates, has greatly improved since the advent of computed tomography (CT). A simple, noninvasive stereotactic system which enables rapid, parallel placement of multiple interstitial catheters for treatment of malignant brain tumors has been developed. Departing from traditional stereotactic methods, the implantation procedure is performed in one stage--entirely in the CT suite. Perioperative nursing responsibilities include mastering the technical aspect of a high precision system as well as meeting the special needs of the patient undergoing this procedure. Initially developed for use in volumetric interstitial brachytherapy, the procedure is now being used in Phase II clinical trials of volumetric interstitial hyperthermia in the management of patients with intracranial malignancies.
立体定向技术，即一种使用三维坐标定位特定点的方法，自计算机断层扫描（CT）问世以来有了很大改进。现已开发出一种简单、无创的立体定向系统，该系统能够快速、平行地放置多个组织间导管，用于治疗恶性脑肿瘤。与传统立体定向方法不同，植入过程在一个阶段内完成——完全在CT检查室进行。围手术期护理职责包括掌握高精度系统的技术方面，以及满足接受该手术患者的特殊需求。该手术最初是为容积性组织间近距离放射治疗而开发的，目前正用于颅内恶性肿瘤患者容积性组织间热疗的II期临床试验。
