Results:There was advantage in showing the figure of lesions by multiple orientation and indicating the plane and space relationships between lesions and peripheral tissues without blind area.
结果：MPR、3D和CTVE重组图像能更好的从多方位显示病变形态及其与周围组织之间平面和空间的关系，无盲区。
The passive orientation of IRST is a dynamic triangle measurement. For the fixed target, the orientation error can be minimized by multiple measurements and the least squares(LS) method.
IRST的被动定位实质上是一个动态三角测量法，对于固定目标，可以利用多次测量和最小二乘法降低定位误差。
