From the echocardiography machine to the lecture room: a simple method for transferring echocardiographic frames and loops to a personal computer

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. IMPLICATIONS: The transfer of frames and loops from echocardiographic machines to personal computers is often useful for publication, teaching, and educational purposes. We present an easy and cost-effective method for transferring frames and loops from any echocardiography machine into a personal computer using a digital video camera.
