[The first system of image transmission and neurosurgical telecommunication in Poland].

OBJECTIVE: The goal was to develop a fast and efficient neurosurgical teleconsulting network to improve acute neurosurgical patient care, to reduce transport costs and unnecessary occupation of neurosurgical beds. METHODS: Modems with 56 kilobits/s data transmission speed are used. CT images are transmitted straight from CT scanner via modem/telephone lines to receiving personal computer in Department of Neurosurgery. Receiving PC runs with Microsoft Windows operating system and the network software MultiView (EMED, Inc.). Network connects Department of Neurosurgery Polish Academy of Sciences in Warsaw with transmitting hospitals in Ciechanów and Ostrołeka. RESULTS: The system is fast, one study consisting 18 images is transmitted in about 5 minutes and it is simple to use, to date more than 1000 CT images have been transmitted. Operator acceptance has been very high. The system has improved acute neurosurgical patient care. Transfer of appropriate patients has been accelerated and unnecessary transfer is almost eliminated. CONCLUSION: Applied Neurosurgical Teleconsulting System has significantly improved acute neurosurgical patient care and has reduced transport expenses. Better availability of neurosurgical consultation has been achieved. The network is simple to use and has gained physician acceptance. It has to be emphasized that the creation and using of the system is relatively not expensive.

Visual telecommunication for expert consultation of intraoperative sections.

Histopathological images of intraoperative sections were transferred by use of normal telephone line between the Department of Pathology, Thoraxklinik, Heidelberg, and the Institute of Pathology, Hospital Baumgartnerhöhe, Vienna. The images were digitized using a colour TV camera and stored in a specific image transmission system (VP2000). The transfer of one image lasted 1.4-2 min at average; normally two different areas of the section were transmitted. The expert discussion including the clinical history usually started a few minutes prior to the image transfer, and was finished 3 min after the transfer of the last image. A substantial assistance in the intraoperative classification of the disease was achieved in 37% of the 35 submitted cases. The images transfer was only useful for medium to high magnifications of the microscope, i.e., an objective x 25 or higher. The trail allows the following conclusions: a) Visual transfer of microscopic images is a useful technique for expert consultation of intraoperative sections, and can give additional information in 20-40% of the analyzed cases; b) it is useful only for medium or high microscopic magnifications and limited by the spatial resolution of the TV cameras.
