Ultrasound is one of the most widely used medical imaging modalities. More than 80 million ultra-sound studies are conducted each year in North America. With the advent of new portable ultrasound systems, new applications are emerging and are being used in over 20 specializations, including diag-nostic imaging and image guided procedures. Compared to other imaging modalities, ultrasound has a number of key advantages, including low cost, ability to produce images in real-time, and does not use ionizing radiation.As a result, it is expected that the demand for ultrasound sonographers will increase by 23% in 2023. On the other hand, ultrasound images are notoriously difficult to interpret, and depend heavily on the expertise of the operator in placing the transducer and adjusting numerous system parameters. Conse-quently, there is a gap is supplying sufficient numbers of trained sonographers to meet this demand. To accelerate training, healthcare education is turning to medical simulation equipment. Indeed this market has grown significantly to about $1 billion in 2013 and is predicted to grow at a CAGR of 20%. We have developed a physics-based computational method that capable of real-time, operator-dependent simulation of any ultrasound mode and across an unlimited variety of virtual organs and pa-thologies. Unlike our competitors who are dependent on pre-recorded data and empirical information, our system simulates the physics of ultrasound. Because of this and early conversations with end-users, we believe we have a compelling advantage in being able to cost-effectively simulate clinically realistic images (including the most important artifacts) in real-time with operator-dependent control parameters and provide the high degree of realism that the market demands. This proposal outlines the development plan leading to end-user focus groups to validate product-market fit.

超声是使用最广泛的医学成像方式之一。每年在北美进行超过8000万个超声研究。随着新的便携式超声系统的出现，新的应用程序正在出现，并且正在20多种专业中使用，包括诊断态度成像和图像引导程序。与其他成像方式相比，超声具有许多关键优势，包括低成本，实时制作图像的能力以及不使用电离辐射的能力。结果，预计对超声超声波检查员的需求将增加23％的2023年。另一方面，超声图像很难解释，并且很大程度上取决于操作员在放置传感器并调整众多系统参数方面的专业知识。坦率地说，存在一个差距正在提供足够数量的训练有素的超声检查员来满足这一需求。为了加速培训，医疗保健教育正在转向医疗模拟设备。实际上，该市场在2013年已大幅增长到约10亿美元，预计将以20％的复合年增长率增长。我们已经开发了一种基于物理学的计算方法，该方法能够对任何超声模式以及无限种类的虚拟器官和PA词进行实时，依赖操作员的模拟。与依靠预录制数据和经验信息的竞争对手不同，我们的系统模拟了超声的物理。由于与最终用户的早期对话和早期对话，我们相信我们可以实时模拟临床现实的图像（包括最重要的伪像），这具有令人信服的优势。市场要求的现实主义程度。该提案概述了开发计划，导致最终用户焦点小组验证产品市场契合度。
