脑图成像系统的研制

An investigation of cerebrograph imaging system

研制了一种诊断脑血管疾病和研究脑功能的医用成像设备。它能定量分析局部大脑血流量（ｒＣＢＦ）并成像，同时还可以记录、定量分析脑电图（ＥＥＧ）并构成地形图．实现了小脑－脑干区及大脑皮层ｒＣＢＦ地形图的测量。该系统首次把核医学成像技术与电生理技术结合起来，以彩色ｒＣＢＦ地形图、ＥＥＧ地形图方式及其定量数据提供了有关脑血流量、脑功能的综合信息．这对脑部疾病诊断，尤其对脑血管疾病的早期诊断有重要价值。

A cerebrograph imaging system was investigated for the diagnosis of cerebrovascular diseases.This system can quantitatively analyse and map the regional cerebral blood flow(rCBF)and also the electroencephalography(EEG).The mapping of cerebellum-brain stem area was also realized. This system is the first one to combine the technology of nuclear medicine with electrophysiology, and thereby provide a combined information about the rCBF and the function of brain with coloured rCBF mapping,topogtaphical EEG mapping and quantitative data at the same time.It has important value for the early diagnosis of brain diseases,especially for the cerebral vascular accident.
