摘　　要：本系统通过对超声图象进行连续采集以后,对每帧图象的相关区域进行亮度及灰度统计,得出各对应区域的灰度变化曲线,再运用曲线拟合方法对各帧图象的灰度变化作出灰度.时间曲线并计算灰度峰值、峰值时刻、前半峰时间、后半峰时间及曲线下的面积等统计数据.本系统对临床诊断及科研都具有一定的实用价值.A B-ultra cardiovascular analyzing system is introduced. By capturing continuing B-ultra cardiovascular image, the statistical values of light and gray in B-ultra cardiovascular image and curve of gray is calculated. And then by the curvefitting algorithm, the gray-time curve of image and gray peak value, the time of peak value, area of image have been gotten. This system is appliable to clinical diagnose and scientific research.
