本研究的目的是通过实验证明高质量三次谐波成像的可行性。为了有效地进行三次谐波检测，提出了一种新的高空间分辨率超声换能器系统，该系统由单独布置的发射/接收超声换能器（SATRUT）和带有电容器和电感器的简单滤波器组成。对球目标的脉冲回波谱、球目标的后向散射图像和海绵体模的 B 模式图像的观察证实了视觉图像空间分辨率的提高，并使用自相关方法定量证明了这一点。
The aim of the present study is to demonstrate, experimentally, the feasibility of third-harmonic imaging with high quality. In order for the third-harmonic detection to be effective, a new ultrasonic transducer system for high spatial resolution, which consists of a separately arranged transmitting/receiving ultrasonic transducer (SATRUT) and a simple filter with a capacitor and a inductor, has been proposed. The observation of pulse echo spectra from a ball target, back-scattered images of it, and B-mode images of a sponge phantom have confirmed the improvement of the spatial resolution in the images visually which is testified quantitatively using an auto-correlation method.
