摘要
设计制作了两种用于三维超声系统体积测定的水中体模和Agar体模。实验结果表明,随着扫描深度的增大,在水中的体积测量误差从4%到7%逐渐增大;在Agar中的体积测量误差从6%到10%逐渐增大。所设计制作的体模与该体积参数的测定方法为建立三维超声诊断仪检测标准以及三维超声系统的临床应用作了初步探索。
This paper addressed the volume measurement of 3D ultrasound imaging system.Two different phantoms used in the measurement of volume of the 3D ultrasound imaging system were built,i.e.,water phantom and agar phantom.The experiments demonstrated that as the increase of scan depth,the volume measurement accuracy is varied from 4% to 7% in water and 6% to 10% in agar.The phantoms and the volume measurement of the 3D ultrasound imaging system provides a basis for the establishment of testing standard and clinical application of 3D ultrasound imaging system.
