In this project a low-loss, phase-continuous ultrasonic Fresnel lens has been developed together with orthographic visualization equipment using the same, for biomedical use. Unlike conventional ultrasonic diagnostic equipment, it takes a form of one-gaze orthographic viewer, and does hire neither beam-forming, nordirectivity synthesis, norline-serial image data acquisition. Initial plan was to make focal-plane imaging plate having per-pixel sensor each by each supported by receiving electronics, however, due to tome and expense restriction the project was switched to make a rotating 1-D stripe array to acquire sinogram of focal plane image followed by CT reconstruction algorithm means. A 50 element, 0.5mm pitch, 25x25mm 1-D stripe array sensor with conventional PZT material, and supporting 50 channel Doppler receiver array, have been fabricated, tested, and model-signaling for validation test has been performed, with success. Rotary support for the FPA (focal plane array) and testing at real environment real data, are yet left for further extension of this project.

在这个项目中，一个低损耗，相位连续的超声菲涅尔透镜已经开发与正交可视化设备使用相同的，用于生物医学用途。与传统的超声诊断设备不同，它采用单目正射观察器的形式，并且不雇用波束形成、无向性合成、无线串行图像数据采集。最初的计划是制作由接收电子设备支持的每个像素传感器的焦平面成像板，然而，由于托姆和费用的限制，该项目被切换到制作旋转的1-D条纹阵列以获取焦平面图像的正弦图，然后是CT重建算法手段。一个50元素，0.5毫米间距，25 × 25毫米一维条纹阵列传感器与传统的PZT材料，并支持50通道多普勒接收器阵列，已制造，测试，并进行了验证测试的模型信号，与成功。焦平面阵列的旋转支撑和在真实的环境下测试真实的数据，还有待于该项目的进一步扩展。
