[Transmission of neurosurgical medical records through computers. Simple reality, considerable progress]

Tests on the transmission of view data processing images were undertaken for 5 months from two experimental micro-processing sites specialized in medical imagery and linked to the R.N.I.S. network. The aim of the research was to validate the equipment and the software, and to find a way of working with regard problems related to long-distance diagnosis. Using an everyday equipment like Apple Macintosh II fx, 75 files were transferred corresponding in 375 images (1% conventional X-ray, 5% digital angiography, 31% scanner and 63% M.R.I.). It has been found that the transfer of medical data is reliable (the images do not deteriorate), easy (less than 3 hours to be familiar with the program) and above all fast (actual transfer time: 8.72 Ko per second). Neurosurgeon and neuroradiologist writers talk about their experience in this field.
