In this research, the primary goal is to develop an automated cervical smear analysis system for use after manual screening of thinlayer cervical specimens as a quality control (QC) instrument. The device will measure nuclear features termed "Malignancy Associated Changes" (MACs) to identify disease in samples that are falsely negative by manual methods. At the current levels of technology and in the present regulatory environment, the development of such a system will play an important role in laboratory quality, and will likely reach the market long before an automated primary screening device. The use of MACs is new and innovative in that it allows fast and accurate processing at a very reasonable system cost. In Phase II a fully automated prototype would be developed and tested. Specific research areas are 1) the optimization of the stain, 2) the use of multiple focal planes, 3) optimization of classifiers, and 4) completion and testing of a completely automated prototype. Specification and design of a commercial instrument will begin at the end of Phase II and continue into Phase III. PROPOSED COMMERCIAL APPLICATION: This device would provide enhanced quality control for Pap test analysis in all cytology laboratories worldwide. The current practice of rescreening 10% of negative smears is not adequate. Implementation of a fast and inexpensive automated system used after manual screening would result in increased accuracy and improved healthcare.

在这项研究中，主要目标是开发自动宫颈 涂抹分析系统用于手动筛选薄层宫颈后 标本作为质量控制（QC）仪器。 该设备将测量 核特征称为“与恶性相关的变化”（MAC）以识别 通过手动方法错误为阴性的样品中的疾病。 在 当前的技术水平以及当前的监管环境， 这种系统的发展将在实验室中发挥重要作用 质量，很可能在自动化初选之前就可以进入市场 筛选设备。 Mac的使用是新的和创新的，因为它允许 以非常合理的系统成本快速准确处理。 在阶段 II将开发和测试全自动的原型。 具体的 研究领域是1）污渍的优化，2） 多个焦点平面，3）优化分类器，4）完成 并测试完全自动化的原型。 规范和设计 商业仪器将在第二阶段结束时开始，并继续 进入第三阶段。 拟议的商业应用：此设备将提供增强 所有细胞学实验室中的PAP测试分析的质量控制 全世界。 当前将10％的负涂片重新纠正的做法是 不够。 实施快速且廉价的自动化系统 在手动筛选后使用将提高准确性和 改善医疗保健。
