动态图像是快速连续显示的一系列静态图像，被人眼感知为连续运动，广泛应用于医学中。远程医疗的主要目标之一是将此类图像传输到远程位置以远程管理临床问题。有多种方法可用于获取、存储、传输和显示这些图像。然而，临床问题的背景决定了这些方法中的哪一种可以部署在远程医疗解决方案中。本文讨论了不同技术的优点和缺点，并介绍了介入心脏病学电话会议系统的示例。该系统采集心脏血管造影和血管内超声图像，并通过现有的互联网连接将其传输到远程位置。它专门针对临床会议进行了优化，与会议准备相对较长的时间相比，会议期间每个病例演示的时间都受到限制。该系统利用这一特性，在临床会议之前传输图像，并在会议期间在两个地点同步显示它们。这样可以保留原始图像质量。
Dynamic images, a sequence of static images displayed in rapid succession and perceived as a continuous motion by the human eye, are widely used in medicine. One of the primary objectives of telemedicine is the transmission of such images to a distant location to manage clinical problems remotely. A broad variety of methods is available to acquire, store, transmit and display these images. However, the context of the clinical problem determines which of these methods can be deployed in a telemedicine solution. This paper discusses the advantages and disadvantages of the different technologies and presents an example of a teleconferencing system for interventional cardiology. This system acquires cardiac angiography and intravascular ultrasound images and transmits them over an existing Internet connection to a distant location. It is specifically optimized for clinical conferencing, where time is limited for each case presentation during the conference, compared to the relatively long time available for the conference preparation. The system takes advantage of this characteristic by transmitting the images well in advance of the clinical conference and displaying them synchronously at both locations during the conference. This allows for the preservation of the original image quality.
