项目摘要

This research proposes a new concept called "e-hospital". Our propose e-hospital unites distributed medical resources such as clinic, hospital and patient's home by the Internet communication technologies. The e-hospital provides integrated high quality medical services with low-cost. This paper describes our newly developed fundamental techniques for our e-hospital.This e-hospital system deals with vital data and medical image data such as CT and MR images. The vital data measured at patient's home is automatically stored in "Vital server of the home" from the measurement devices. The stored vital data will be transmitting to "Home doctor's server" via Internet. Hospital imaging center also transmit the patient's medical images to the Home doctor's server via Internet. Home doctor's server integrates these patient's vital data and medical images automatically. The e-hospital provides secured Internet communication for these data transfer by using our proposed watermarking techniques. … More This watermarking technique has two functions. One is to hide the medical image in dummy images for discourage cracking image servers. Another one is for automatically inserting a copyright image into the medical images preserving originality and ownership of the medical images. By using our proposed watermarking technology, medical images are protected.The transmitting time for patient's one-month watermarked vital data (6.67kB) is about 0.14 sec via Internet. And the transmission time of one watermarked CT study (200slices) is about 74 second with the same transmission condition. The extracted medical images possess good quality for physician's diagnosis. Moreover, it is possible to consult freely in e-hospital system through the TV camera between the patient and the home doctor. The patient was satisfied in doing an enough consultation as the home doctor with e-hospital system.The e-hospital deals with not only medical image data but also patient vital data. That is, the region functions as one hospital. The e-hospital system that uses a secured Internet communication becomes a total patient health care system, which connects patients, home doctors, and hospital imaging centers. Less

本研究提出了一个新的概念，称为“电子医院”。我们提出的电子医院是利用网际网路通讯技术，将分散在各地的诊所、医院、病人家中等医疗资源整合起来。电子医院以低成本提供高质量的综合医疗服务。本文介绍了我们最新开发的电子医院的基本技术。这个电子医院系统处理生命数据和医学图像数据，如CT和MR图像。在患者家中测量的生命数据将从测量设备自动存储在“家中的生命服务器”中。储存的生命数据将通过互联网传输到“家庭医生的服务器”。医院影像中心也通过互联网将病人的医学影像传输到家庭医生的服务器上。家庭医生的服务器将这些病人的生命数据和医学图像自动集成。电子医院提供安全的互联网通信，这些数据传输，通过使用我们提出的水印技术。 ...更多信息该水印技术具有两个功能。一种是将医学图像隐藏在虚拟图像中，以阻止破解图像服务器。另一种是用于将版权图像自动插入到医学图像中，从而保持医学图像的原始性和所有权。利用我们所提出的浮水印技术，可以保护医学影像，病人一个月的生命资料（6.67kB）在网际网路上的传输时间约为0.14秒。在相同的传输条件下，一个带水印的CT研究（200层）的传输时间约为74秒。提取的医学图像具有良好的质量，为医生的诊断。此外，通过患者和家庭医生之间的电视摄像机，可以在电子医院系统中自由咨询。病人满意地做了足够的咨询作为家庭医生与电子医院系统。电子医院不仅处理医学图像数据，而且病人的生命数据。也就是说，该地区作为一个医院运作。使用安全的互联网通信的电子医院系统成为一个完整的患者医疗保健系统，它连接患者、家庭医生和医院成像中心。少
