The chief relevance of telemedicine lies in its capability to link medical practitioners and remote hospitals to larger or specialized facilities in a very fast electronic manner. This may become even more important due to current increase in subspecialization and demand for more precise diagnosis and consultation in difficult cases. A network attaching small clinics or laboratories to larger and more specialized units, and to highly specialized referral centers may improve the professional standard of health care services and education. For a wider use, a technological standardization will be required, since the existence of several types of computer and numerous image manipulation programs, have resulted in a proliferation of file formats. However, every potential user or client of telemedicine should keep in mind, that standardization also includes legal and ethical issues such as patient confidentiality and malpractice avoidance. The adoption of workable guidelines and protocols is required. Telepathology in general and teleneuropathology in particular is the practice of pathology at a distance, viewing digitized images of histological slides on a video monitor rather than directly through a light microscope. For the transmission of the digitized images from a telemicroscope to the remote diagnostic video monitor, different technologies such as ordinary telephone lines, broadband telecommunications channels, and the Internet can be used. The transmitted images may serve for primary neuropathological diagnosis, teleconsultation, quality assurance, proficiency testing, and distance learning. Static-imaging and dynamic-imaging are the two major competing technologies of telemicroscopy. Static-imaging systems appear to have levels of diagnostic accuracy which are not satisfactory for diagnostic neuropathology. On the contrary, high levels of diagnostic accuracy can be achieved using dynamic-imaging systems with the transmission of live video images in real time and by using a robotized telemicroscope with the possibility to examine the entire histological specimen under control of the remote teleneuropathologist.
远程医疗的主要意义在于它能够以非常快速的电子方式将医生和偏远地区的医院与更大或更专业的机构连接起来。由于目前专科化程度的提高以及对疑难病例更精确诊断和会诊的需求,这一点可能会变得更加重要。将小型诊所或实验室与更大、更专业的单位以及高度专业化的转诊中心连接起来的网络,可能会提高医疗保健服务和教育的专业水平。为了更广泛地应用,需要进行技术标准化,因为存在多种类型的计算机和众多图像处理程序,导致文件格式激增。然而,远程医疗的每一个潜在用户或客户都应该记住,标准化还包括法律和伦理问题,如患者保密和避免医疗事故。需要采用可行的指导方针和协议。一般的远程病理学,特别是远程神经病理学,是一种远程进行病理学诊断的实践,通过视频监视器查看组织学切片的数字化图像,而不是直接通过光学显微镜观察。为了将数字化图像从远程显微镜传输到远程诊断视频监视器,可以使用不同的技术,如普通电话线、宽带电信通道和互联网。传输的图像可用于原发性神经病理学诊断、远程会诊、质量保证、能力测试和远程学习。静态成像和动态成像是远程显微镜的两种主要竞争技术。静态成像系统的诊断准确性水平对于神经病理学诊断来说并不令人满意。相反,使用动态成像系统,实时传输实时视频图像,并使用带有远程神经病理学家控制下检查整个组织学标本可能性的机器人远程显微镜,可以实现高水平的诊断准确性。
