Stereotactic body radiotherapy uses the principle of 3-dimensional localization of a target to deliver a high dose of radiation to a precise location. The aim of this technique is to ablate tissue noninvasively. Because of its high precision and target conformity, it can deliver a high dose of radiation to a specific area in a tissue without significantly affecting nearby tissues. It is being actively studied and even used in therapy for atrial fibrillation and ventricular tachycardia.
立体定向体部放射治疗利用靶点三维定位原理，将高剂量辐射精准投送至特定位置。该技术旨在无创消融组织。因其高精度和靶区适形性，它能在不显著影响附近组织的情况下，向组织内特定区域输送高剂量辐射。目前正在积极研究该技术，甚至已用于心房颤动和室性心动过速的治疗。
