Medline ® Abstract for Reference 65

Two video techniques are commonly used for biomedical monitoring. The simplest technique uses 2 or 3 video cameras with a special-effects generator. The more advanced method uses one video camera with a reformatter, a special-effects generator and a time-code generator. The main components of a video recording system are the camera, tape recorder, monitor, special-effects generator, reformatter, audio system and time-code generator. Video recordings can be edited electronically, but the quality of the copies is dependent on the type of editing equipment and the technical expertise available. Video recording has helped to improve the diagnosis and treatment of seizures and has been widely used in clinical epilepsy research. Video monitoring is now generally available in large medical centers for the diagnosis of difficult patients.
