SBIR Phase II: New Liquid Crystal Materials for Breast Cancer Imaging and Other Medical and Industrial Applications

小行星940774 该小型企业创新研究（SBIR）第二阶段项目将开发更高灵敏度的基于液晶的超声（声学）探测器。 低灵敏度一直是限制声光显示器的工业应用以及限制医疗应用的因素。 研究了第一阶段的新液晶系统，发现其可将检测灵敏度提高一个数量级或更多。 第二阶段的开发预计将增加一个或两个数量级的改进，并建立一个原型系统，用于进一步研究医疗和工业应用，例如，乳腺成像用于癌症检测和工业材料的无损检测。

940774 Sandhu This Small Business Innovation Research (SBIR) Phase II project will develop higher sensitivity of liquid-crystal based ultrasound (acoustic) detectors. Low sensitivity has been a factor limiting industrial applications of acousto-optical displays as well as limiting medical applications. Phase I new liquid crystal systems were studied and found to improve detection sensitivity by one order of magnitude and more. Phase II development is expected to add another one or two orders-of-magnitude improvement and to build a prototype system for further investigations of medical and industrial applications, e.g., breast imaging for cancer detection and nondestructive inspection of industrial materials.
