DESCRIPTION (provided by applicant): The objective of this project is to use a super high-resolution, large area ultrasound detector called acousto-optic (AO) sensor to record an ultrasound hologram of the breast, from which a 3D volume breast image can be generated instantly (analogously to optical holography). Successful completion of this work will provide a superior 3D volume breast imaging methodology, where the need for physical movement of the 1D transducer array is circumvented. Moreover, the AO sensor employed overcomes the challenges posed by large number of electrical connections and interconnects needed for 2D transducer arrays. Successful completion of this work may provide a superior breast cancer screening process. In Phase I, the goals are to first construct a laboratory breast imaging system based on the AO sensor and test feasibility of such a system to produce instant 3D breast images using phantoms. PUBLIC HEALTH RELEVANCE: The successful development of the proposed holography technique using the AO sensor could enable generation of an instant, full-field 3D volumetric image of the breast, circumventing the need for physical movement of the ultrasound probe. The resulting image would allow a more accurate localization of the suspicious indications on a mammogram, which could result in improved breast cancer screening.

描述(申请人提供)：该项目的目标是使用一种名为声光(AO)传感器的超高分辨率、大面积超声探测器来记录乳房的超声全息图，由此可以立即生成3D体积乳房图像(类似于光学全息术)。这项工作的成功完成将提供一种优越的3D体积乳房成像方法，其中绕过了1D换能器阵列的物理移动的需要。此外，所采用的声光传感器克服了2D换能器阵列所需的大量电气连接和互连带来的挑战。这项工作的成功完成可能会提供一个更好的乳腺癌筛查过程。在第一阶段，目标是首先建立一个基于声光传感器的实验室乳房成像系统，并测试这种系统使用幻影产生即时3D乳房图像的可行性。与公众健康相关：拟议的使用AO传感器的全息技术的成功开发可以生成即时的、全视野的乳房3D体积图像，而不需要超声探头的物理移动。由此得到的图像将使乳房X光照片上的可疑适应症得到更准确的定位，这可能会导致乳腺癌筛查的改进。
