title: [Digital recording in neurosurgery].
abstract: The purpose of this study is to examine the image quality of multi-media for digital recording of surgical procedure using an operating microscope in neurosurgery. For video recording, high vision recording, digital video recording and analogue VHS recording were used. For still pictures, an analogue camera with 35 mm silver halide film and a micro-digital camera were used. The quality of photographs taken with a microdigital camera was superior to the quality of those taken with the conventional 35 mm film camera. The micro-digital camera system is superior to the conventional 35 mm camera in neurosurgery in its quality and success rate. In video recording, high vision analogue recording was superior to any other media as far as its image quality is concerned although its practical convenience is limited and cost performance is not always good. On the other hand, digital video can record high quality images, including still pictures, with satisfactory quality to the neurosurgeon. These digital recording media are also space saving for storing the huge amount of data obtained during surgery and the cost-performance is superior to that of the conventional method. In the near future, most of surgical procedures are supposed to be expected using digital media.
