摘要我们提出了一种新的超声多普勒-回波可视化方法，该方法有望利用超声速度剖面仪实现无损可视化。可视化使用超声速度剖面仪通常使用的多普勒速度和回波强度的信息来获得瞬时速度剖面。通过对具有不同声阻抗、果肉硬度、形状和内部结构的橡皮球、苹果和番茄的测量，证实了该方法的可行性。讨论了利用超声速度轮廓仪获取被测物体内部结构图像的数学关系和图像处理参数。对测试对象的试验测量表明，多普勒速度和回波强度反映了测试对象的不同特征。利用多普勒速度和回波强度，可以可视化物体的轮廓和内部结构。
AbstractWe proposed a novel ultrasonic Doppler–echo visualization method that is expected to realize nondestructive visualization using an ultrasonic velocity profiler. The visualization uses information of both the Doppler velocity and echo intensity that have usually been used by the ultrasonic velocity profiler to obtain instantaneous velocity profiles. The feasibility of the method is confirmed by measurements of a rubber ball, apple, and tomato having different acoustic impedances, pulp hardnesses, shapes, and inner structures. Mathematical relations and image processing parameters were discussed to obtain images of the inner structures of test objects using the ultrasonic velocity profiler. Trial measurements of test objects elucidated that the Doppler velocity and echo intensity detect different features of the test objects. Using the Doppler velocity and echo intensity, the outlines and inner structures of the objects can be visualized.Graphical abstract
