DESCRIPTION (provided by applicant): This Small Business Innovation Research Phase II project involves the research and development of a real-time FPGA-based volume rendering system. Medical radiologists face a data overload crisis that is getting worse with each year. This crisis is caused by ongoing advances in diagnostic imaging technologies (i.e. CT, MR and ultrasound) that produce more images with higher resolution each year. Compounding this problem is the fact that the number of imaging studies is also growing each year. Current hardware and software solutions are not up to the challenge. As a result, important data is often overlooked producing inaccurate medial diagnoses. The goal of this project is to develop a low-cost FPGA-based volume render that will alleviate this data overload crisis. By eliminating data that does not contribute to 3D images, the volume Tenderer's performance will far exceed current solutions. By being based on FPGAs, the volume renderer will be upgradeable, allowing for future performance and functionality enhancements. Additionally, the renderer will support very high quality renderings through the use of higher-order gradients. Thus, the volume renderer will appeal to users in many markets, including: medical diagnostic imaging, oil exploration, security inspection and engineering simulations. One very exciting application of the 4D capabilities of the volume renderer will be in multi-slice CT cardiac imaging, enabling non-invasive procedures to be performed in place of current invasive procedures. As a consequence, the nation stands to benefit from productivity increases and improved health care. The volume renderer developed in this project will enable very large 3D and 4D data sets, generated by CT and MR scanners, to be viewed in real-time. This will make medical imaging more accurate and useful, improve the radiological workflow and speed up the discover of drugs. In addition, new high-end application such as 4D cardiac rendering will become possible.

描述(申请人提供)：本小企业创新研究二期项目涉及研发基于现场可编程门阵列的实时体绘制系统。医学放射科医生面临着一年比一年严重的数据过载危机。这场危机是由诊断成像技术(即CT、MR和超声波)的不断进步造成的，这些技术每年都会产生更多分辨率更高的图像。使这一问题雪上加霜的是，成像研究的数量也在每年增长。目前的硬件和软件解决方案不能满足挑战。因此，重要的数据经常被忽视，从而产生不准确的医疗诊断。本项目的目标是开发一种低成本的基于现场可编程门阵列的体渲染，以缓解这种数据过载危机。通过剔除对3D图像没有贡献的数据，批量投标器的性能将远远超过当前的解决方案。通过基于现场可编程门阵列，体积呈现器将是可升级的，从而允许未来的性能和功能增强。此外，该渲染器将通过使用高阶渐变来支持非常高质量的渲染。因此，体积渲染器将吸引许多市场的用户，包括：医学诊断成像、石油勘探、安全检查和工程模拟。体积渲染器的4D功能的一个非常令人兴奋的应用将是多层CT心脏成像，使非侵入性程序能够取代目前的有创性程序。因此，国家将从生产率的提高和医疗保健的改善中受益。在该项目中开发的体积渲染器将能够实时查看由CT和MR扫描仪生成的非常大的3D和4D数据集。这将使医学成像更加准确和有用，改善放射工作流程，加快药物发现。此外，4D心脏成像等新的高端应用将成为可能。
