Ultrasound is widely used both for medical diagnostic and therapeutics as well as for many industrial applications. Its importance for medical diagnosis arises from its non-invasive nature and its ability to provide images and quantitative information in a relatively economical manner using systems that are not much larger than a lap-top computer. Diagnostic systems make use of transducers that emit the ultrasound and gather the reflected signal so as to create structural images or to image blood flow. They have a number of limitations which, with the help of new ideas and improvements in signal and image processing, should enable their performance to be further enhanced. In this grant application several sub-topics are proposed, some of which address current limitations and some consider issues directly related to diagnostic applications. In what follows below, just two of the topics are detailed.

超声被广泛用于医学诊断和治疗以及许多工业应用。其对于医学诊断的重要性源于其非侵入性性质以及其使用不比膝上型计算机大得多的系统以相对经济的方式提供图像和定量信息的能力。诊断系统利用发射超声并收集反射信号的换能器，以便创建结构图像或对血流进行成像。它们有一些局限性，在信号和图像处理方面的新想法和改进的帮助下，应能使它们的性能得到进一步提高。在这个补助金申请提出了几个子课题，其中一些解决当前的限制和一些考虑的问题直接相关的诊断应用。在下面的内容中，仅详细介绍其中两个主题。
