[Telecommunication--a medium for improving prenatal diagnosis and gynecologic ultrasound diagnosis? Initial experiences].
To establish the requirements for real-time transfer of an ultrasound examination via telecommunication network the following tests were performed: The ultrasound data were transferred from the video out of an ultrasound system to a basis terminal of the German Telekom. Simultaneously, an external video camera filmed the positioning and movements of the ultrasound transducer, and the verbal comments were recorded. These informations were transmitted to Karlsruhe and London, where they were rerouted to the examination room in Heidelberg. Here the informations were received on a Telecom reception unit/terminal and compared directly with the initial signal. The quality was sufficient if the moving ultrasound images and the camera image of the transducer as well as the oral comment were transmitted over 2 parallel ISDN lines. The delay to a real-time transmission of the examination process is only in the range of milliseconds. If only one ISDN line is used, the image quality is unsatisfactory, three parallel lines do not bring significant improvement of image quality. Telemedicine seems a new possibility to bring the knowledge of specialized centers to the practicing gynaecologists thus avoiding unnecessary referrals. Still unanswered, however, are the problem of liability, data protection and costs.
