脑立体定向即通过一种参照技术准确地定出脑内某目标(病变或正常解剖结构)的三维坐标,并到达该目标进行诊断和治疗。用CT进行脑立体定向具有独到之处,本文就迄今报道的CT脑立体定向系统及其临床应用作一介绍。历史和现状立体定向外科的原理是由Horsley和Clark于1908年提出的,四十年代末由Spiegel和Wycis用于外科实践。当时的主要兴趣是在神经生理学方面。随着神经放射学手 Stereotactic stereotactic refers to the accurate determination of a three-dimensional coordinate of a target (lesion or normal anatomy) in the brain through a reference technique, and reaches the target for diagnosis and treatment. Stereotactic stereotactic CT has its unique features. This article introduces the CT stereotactic system and its clinical application reported so far. History and current status The principle of stereotactic surgery was proposed by Horsley and Clark in 1908 and by the late 1940s by Spiegel and Wycis for surgical practice. The main interest at that time was in neurophysiology. With neuroradiology hands
