DESCRIPTION (Verbatim from the Applicant's Abstract): Bedside radiography is one of the few fields of radiology in which there is no commercially viable means of controlling scattered radiation. This is due to the difficulty in aligning the focal spot with an anti-scatter grid. X-ray scatter therefore often reduces the contrast in bedside radiographs by a factor of 10 or more. This problem is exacerbated in digital imaging systems, which are usually more sensitive to scatter than conventional systems. A practical and convenient solution to this problem is proposed. The goal of Phase I will be to build and evaluate the proposed sensor subsystem, and of Phase II to produce a complete preproduction system and to demonstrate its clinical utility. PROPOSED COMMERCIAL APPLICATION: This invention is directly applicable to bedside and mobile radiography.

描述(逐字摘自申请者摘要)：床边X光片是 少数几个在商业上没有可行性的放射学领域之一 控制散射辐射的手段。这是由于在 将焦点与防散射网格对齐。因此，X射线散射 通常将床边X光片的对比度降低10倍或更多。 这个问题在数字成像系统中加剧，数字成像系统通常 比传统系统对散射更敏感。一种实用便捷的 针对这一问题提出了解决方案。第一阶段的目标将是建立和 评估拟议的传感器子系统，并在第二阶段生成完整的 预生产系统，并展示其临床应用。 建议的商业应用： 本发明直接适用于床边摄影和流动摄影。
