A High Performance Digital Medical Data Link Technology

描述（由申请人提供）： 物理光学公司（POC）提出开发一种新的软计算超压缩交互式无损和有损（SCHILL，“技能”）系统，用于数字临床成像-糖尿病视网膜成像，乳腺癌X射线摄影，肺癌CT和前列腺癌MRI。SCHILL将成为国家医学图书馆和医学信息学的宝贵工具。POC的SCHILL系统将与安全机制和协议兼容，以保护通过互联网传输的医学成像数据。在第一阶段，POC完成了压缩引擎的初步原型开发，展示了10：1的感知无损压缩，将铜线的带宽距离乘积从10 Mbps/km增加到100 Mbps/km，并成功地进行了一系列测试，作为工程环境中的临床成像评估。在第二阶段，POC将开发一个优化的SCHILL系统，该系统将包括接口和视频编码器IC卡，用于>20：1或更高的感知无损压缩，其余元素如PC工作站和图形卡将是COTS组件。在第二阶段，将由约翰霍普金斯大学应用物理实验室对SCHILL系统进行全面的临床评价，并将在BromartCommunications，Inc.进行网络试验台评价。

DESCRIPTION (provided by applicant): Physical Optics Corporation (POC) proposes to develop a new Soft Computing Hypercompression Interactive Lossless and Lossy (SCHILL, "skill") system for digital clinical imagery - retinal imaging for diabetes, x-ray mammography for breast cancer, CT for lung cancer, and MRI for prostate cancer. SCHILL will be a valuable tool for the National Library of Medicine and medical informatics. POC's SCHILL system will be compatible with security mechanisms and protocols that protect medical imaging data traveling over the Internet. In Phase I, POC completed the preliminary prototype development of a compression engine that demonstrated 10:1 perceptually lossless compression, increasing the bandwidth-distance product of a copper line from 10 to 100 Mbps/km, and successfully performed a series of tests as a clinical imagery evaluation in an engineering setting. In Phase II, POC will develop an optimized SCHILL system that will include interfaces and a video encoder IC card for >20:1 or higher perceptually lossless compression, such remaining elements as the PC workstation and graphics card will be COTS components. In Phase II, a thorough clinical evaluation of the SCHILL system will be performed by The Johns Hopkins University Applied Physics Laboratory, and a network testbed evaluation will be conducted at Broadata Communications, Inc.
