摘要: 阐述了基于边缘检测的超声膀胱容积测量算法。通过超声膀胱测容仪的三维超声探头对膀胱沿轴向作180度扫描,获取12张不同截面的膀胱超声图像,对该组超声图像经图像预处理后进行边缘检测构造出膀胱的三维模型,并运用空间立体体积的积分法快速估算出膀胱的容积。该算法已经运用于超声膀胱测容仪PBSV 3.1上,在临床实验中平均误差在12%以内。

Abstract: A volume measurement algorithm based on edge detection was introduced in this paper. The algorithm was applied to the portable system for measuring bladder volume. In the system, the three-dimensional ultrasound probe performed the scanning with the axial angle of 180 degree. Twelve axial sections of a bladder with the same scanning interval were obtained and used to edge extraction. The group of bladder edges formed a three-dimensional bladder body and the integral method of spatial volume was used to calculate the bladder volume.The average error of the algorithm in clinical diagnosis experiment was within 12%.

Key words: edge detection, bladder, volume measurement, three-dimensional ultrasound scanning
