A two-station, closed-circuit, black-and-white television system is currently being used on a day-to-day basis to transmit microscopic images between two facilities at these Laboratories. Transmitted images are of sufficient quality to allow critical study and diagnosis of tissue slides by pathologists. Electronic components include a Vidicon television camera, a 17-in. monitor, a video-equalizing amplifier, and a send-receive switch. The camera is transistorized, entirely self-contained, and requires no lens for television microscopy. Station-to-station distances are 1,900 ft on a direct line, 2,400 ft along the transmission line, and about 4,400 ft by roadway. Image magnifications on the monitor screen are about 200X, 600X, and 2,500X. The use of an expanded system for direct consultation between pathologists in geographically separated laboratories is discussed. Author
