The use of computers in scientific and educational presentations is rapidly increasing. As a digital presentation is ideal for showing moving images, the use of multimedia files, e.g., echocardiographic loops within these presentations, is common. Even though recent echocardiography machines store acquired data in a digital format, these data are often not readily accessible to be transferred to a personal computer. We present an easy and cost-efficient method for transferring frames and loops from any echocardiography machine into a personal computer using a digital video camera equipped with a standard analog input and flash memory. Still images and movies are stored in the camera to be subsequently transferred to a personal computer. In the computer, still images and movies are post-processed with graphical and video editing software. Finally, the still images and movies can be projected from the video camera or presented with specialized software such as PowerPoint. The images can also be used for Web-based publications and production of educational material or books on electronic media such as CD-ROM. The described method can also be used to transfer images from other proprietary devices and programs, as long as the devices are equipped with an analog video outlet.

计算机在科学和教育演示中的应用正在迅速增加。由于数字演示对于展示动态图像非常理想，因此在这些演示中使用多媒体文件（例如超声心动图循环）很常见。尽管最近的超声心动图机器以数字格式存储采集到的数据，但这些数据通常不容易获取以便传输到个人计算机。我们提出了一种简单且经济高效的方法，使用配备标准模拟输入和闪存的数字摄像机将任何超声心动图机器中的帧和循环传输到个人计算机。静态图像和电影存储在摄像机中，随后传输到个人计算机。在计算机中，静态图像和电影使用图形和视频编辑软件进行后期处理。最后，静态图像和电影可以从摄像机投影出来，或者使用诸如PowerPoint之类的专业软件进行展示。这些图像还可用于基于网络的出版物以及制作教育材料或电子媒体（如CD-ROM）上的书籍。只要设备配备模拟视频输出，所描述的方法也可用于从其他专有设备和程序传输图像。
