This SBIR Phase II research project strives to develop an Advanced Ultrasonic Beamformer that is unparalleled in its scalability and signal processing features. The ultrasonic beamformer architecture will be unique in its breadth of features. The architecture was developed as the superset of features across several fields including medical imaging, medical therapy, bone density measurement, vascular imaging, and materials characterization. This approach provides each field with an instrument capable of operating outside the normal performance envelope, thereby presenting opportunities for the development of new uses of ultrasound. The benefits of this array include better frame rates, crisper images, and more accurate surgery. The higher frequencies used in materials characterization, when brought to medical imaging, will allow array transducer to be used where only conventional, single element probes could used in the past, for example in intra-cardiac imaging for surgical instruments, and also for tumor ablation. By design, the proposed architecture encompasses the abilities of many different fields. Each field then enjoys performance capabilities beyond what is normally available, providing a general-purpose tool for research.

该SBIR II期研究项目旨在开发一种高级超声波束形式，该超声梁形式在其可伸缩性和信号处理功能方面是无与伦比的。超声波束形架构在其广度上将是独一无二的。该体系结构是在多个领域的特征的超集开发的，包括医学成像，医疗疗法，骨密度测量，血管成像和材料表征。这种方法为每个字段提供了能够在正常性能信封之外运行的仪器，从而为开发超声的新用途提供了机会。该阵列的好处包括更好的帧速率，更清晰的图像和更准确的手术。将材料表征中使用的较高频率带入医学成像时，将允许在过去只能使用常规的，单元素探针的情况下，例如用于手术仪器内部成像，也可以用于肿瘤消融。根据设计，所提出的体系结构涵盖了许多不同领域的能力。然后，每个字段都具有超出通常可用的功能的性能功能，为研究提供了通用工具。
