Nearly ten years have passed since telepathology was introduced and real-time pathology consultations were conducted. Long distance consultations in pathology, cytology, computed tomography and magnetic resonance imaging, which are referred to as telemedicine, clearly enhance the level of medical care in remote hospitals where no full-time specialists are employed. To transmit intraoperative frozen section images, we developed a unique hybrid system "Hi-SPEED". The imaging view through the CCD camera is controlled by a camera controller that provides NTSC composite video output for low resolution motion pictures and high resolution digital output for final interpretation on computer display. The results of intraoperative frozen section diagnosis between the Gihoku General Hospital 410 km from SRL showed a sensitivity of 97.6% for 82 cases of breast carcinoma and a false positive rate of 1.2%. This system can be used for second opinions as well as for consultations between cytologists and cytotechnologists.
