研制了一套用于133Xe吸入法局部脑血流量(RCBF)测量的计算机多探测器系统。该系统的计算机部分具有在线数据采集、快速数据分析和结果显示的特点。特殊的系统功能包括在流量测量的饱和和减饱和阶段自动确定潮气末氙气浓度的程序，以及提供自动背景减去的程序，以及专用的反数字多路复用器-计算机接口。该系统为处理急病患者提供了便利，并确保了连续测量的重复性定位。给出了150例患者和正常受试者测量的典型输出格式和部分结果。
A computer based multidetector system was developed for the measurement of regional cerebral blood flow (rCBF) by the133Xenon inhalation technique. The computer portion of the system is characterized by on-line data acquisition, rapid data analysis and presentation of results. Special system features include programs which automatically determine end-tidal Xenon concentrations during the saturation and desaturation phases of the flow measurement and which provide for automatic background subtraction, and a special purpose counter-digital multiplexor-computer interface. The system provides convenience in handling acutely ill patients, and assures reproducible positioning for serial measurements. Typical output format and partial results from 150 patient and normal subject measurements are presented.
