心脏储备指标数据处理和信息管理系统的研究与应用

Research and application of cardiac reserve data processing and information management system

背景:目前国内评价心脏储备功能的方法大都是在静息状态下测量心脏性能指标。经过查阅文献国际文献资料,了解到由于心脏衰竭时心脏功能失常最重要的方面不是在基础静息状态下观察到的心脏性能抑制,而是心脏储备的丧失。目的:利用目前超声诊断领域广泛使用的B超诊断仪,以前期实验得到的结论作为依据,开发一套能够具备课题所要检测心脏储备指标的数据处理能力和信息管理能力的系统,对受试者运动前后心脏储备功能进行分析,旨在为课题提供方便的技术支持,并为完善现有的B超诊断仪提供改进依据。方法:通过图像采集卡的连接将普通B型黑白超声诊断仪作为PC外设,研究并开发了包含心脏专业图像采集处理和完善的资料库管理在内的超声心脏图像诊断和管理系统。结果与结论:该系统实现了包括图像增强、几何参数测量在内的多个图像处理和分析功能,可提供便捷的诊断报告生成、方便的档案管理及打印功能,实现了一个高效灵活的小型医学影像和通信系统。结果提示系统借助PC强大的处理能力可显著扩展和提升传统超声诊断仪在检测心脏储备方面的性能,为课题实验提供了有力的技术支持,为医生在检测心脏储备指标方面提供了新的系统支持。

BACKGROUND： Cardiac reserve indicators obtained under quiescent condition are used as evaluating index for cardiac reserve functions. However, most important aspect of cardiac dysfunction in heart failure is not the depressed cardiac performance noted at basal resting states, but rather the loss of cardiac reserve. OBJECTIVE： To develop a data processing and information management system for detecting cardiac reserve indicator with the widely used B mode ultrasound instrument in the ultrasonography field, and to provide guidance for B mode ultrasound instrument perfection. METHODS： General B mode ultrasound instrument as peripherals was connected with the pc by image acquisition card; ultrasound heart image diagnosis and management system including professional heart image acquisition and process and perfect data bank was develop. RESULTS AND CONCLUSION： An efficient and flexible mini picture archiving and communication system system was achieved, which realized image enhancement, geometric parameter measuring, convenient diagnosis report output, archive management and print function. Results demonstrated that with the powerful data process ability of PC, the system could improve the performance of the traditional ultrasound instrument in detecting cardiac reserve, which provide a powerful support for the further study.
