在这项工作中，我们展示了利用中心频率为5.5 MHz的二维电容式微机械超声换能器(CMUT)阵列对嵌入在高散射背景介质中的深度为5 cm的光学吸收目标进行三维光声成像。给出了三维体积图像和二维最大强度投影图像，以显示不同深度的物体。由于CMUT非常接近集成前端电路，因此CMUT阵列成像系统具有低噪声底板。这使得CMUT成为一种很有前途的深部组织光声成像技术。
In this work, we demonstrate 3-D photoacoustic imaging of optically absorbing targets embedded as deep as 5 cm inside a highly scattering background medium using a 2-D capacitive micromachined ultrasonic transducer (CMUT) array with a center frequency of 5.5 MHz. 3-D volumetric images and 2-D maximum intensity projection images are presented to show the objects imaged at different depths. Due to the close proximity of the CMUT to the integrated frontend circuits, the CMUT array imaging system has a low noise floor. This makes the CMUT a promising technology for deep tissue photoacoustic imaging.
