Adaptive Signal Synthesis for Biomedical Ultrasonic Imaging

9701440 Jaffe生物医学超声成像是一种重要的非侵入性方法，可以诊断多种类型的心血管疾病。 不幸的是，当观察体内太小或太深的血管时，该方法失败，因为这些特征反射很少的入射声音。 我们发明了一种规避这些传统限制的方法，包括测量这些结构反射率的特殊特征，然后聚集专门针对其反射量身定制的定制声纳波形。 这笔赠款将资助体外和体内实验，这将使我们能够在实验室和临床研究中改进和验证该方法的实用性。 ***

9701440 Jaffe Biomedical ultrasonic imaging is an important nonivasive method which permits the diagnosis of many types of cardiovascular disease. Unfortunately, the method fails when viewing blood vessels that are either too small or too deep inside the body because these features reflect very little of the incident sound. A method that we have invented to circumvent these conventional limitations consists of measuring the special characteristics of the reflectivity from these structures and then crowing custom made sonar waveforms which have been specifically tailored to their reflections. This grant will fund both in-vitro and in-vivo experiments which will allow us to both refine and verify the utility of the method in the lab and also in clinical studies. ***
