摘要
该系统包括ＰＣ／３８６微机，自制的信号输入器及２４针打印机。软件包括６个功能模块：操作指导，采样，数据管理，频谱分析，相关分析及声图。分析图形及参数表可屏幕显示或打印绘图。彩色声图可显示三维图象，即时间、频率及强度关系图。声图中设置可移动光标，用于选择某时刻详细进行频谱与相关分析。临床应用征明，该系统可获得喉疾病早期诊断信息。
The system includes microcomputer PC/386, self-made signal input device and 24 pin printer.The software of the system consists of 6 function modules: operation instruction,sampling, management of data,analysis of spectrogram,correlogram and sonagram.Graphs and parameter tables can be displayed on the screen or printed out.The color sonagram shows image in three dimensions of time,frequency and intensity.Mobile cursor devised in the sonagram can be used to select some time points to analyse in details with sepectrograms and corresponding parameters. Clinical application proved that information for early diagnosis of laryngeal disease can be obtained with the system.
