摘要 目的:实验研究三维超声体积自动测量系统不同旋转角度对规则物体体积测量准确性的影响。方法:对14个规则形状实验模型作三维扫查,然后分别在30°、15°、9°、6°这4种不同角度下测量其体积。结果:不同旋转角度对规则形状的模型体积测量准确性很高,与实际体积无明显差异(P>0.05);不同旋转角度测量值与实际体积高度相关(P<0.05);30°与其他旋转角度测量值接近,之间无明显差异(P>0.05);不同旋转角度测量体积平均耗时分别为1.26min(30°)、2.43min(15°)、3.56min(9°)和6.18min(6°)。结论:对于规则形状物体体积测量,不同旋转角度对准确性无明显影响;30°旋转角度准确性高,且省时省力。
