医学图像的计算机辅助测量

Computer-Aided Measurement of Medical Image

医学图像检查根据确定的比例尺进行相应参数测量。长度采用平面内两点间距离,角度用两边和水平线的夹角之差,周长以多边形逼近曲线,并采用区域颜色筛选法,通过测量区域的总像素和图像的总像素之比获取包围测量区域的最小矩形。

For inspection measuring of medical image, the corresponding parameters are measured according to defined scales. The distance between the two dots of one plane is used as the length, the inclination of the two corner edges and the horizontal line is used as the angle, and the curves are approximated the perimeter by way of polygons. The least rectangle of the enclosed metrical district was achieved with filtration method of region color according to the proportion between general pels of the measured district and the image.
