Paper Abstract

The objective of this study is firstly to define system configuration for an interactive telesurgery with open MRI, and secondly to elucidate optimum bandwidths of B-ISDN in the standpoint view of functionality to cost ratio. The test bed of B-ISDN network was established between Osaka University Hospital (OUH) and Kawasaki Hospital (KH). The interactive telesurgery has divided into three phases. Phase 1 is to transfer DICOM data of a patient from KH to OUH where image files are archived for data processing. Phase 2 is to make interactive videoconferencing with simultaneous sharing of the DICOM images. Phase 3 is to assist surgical navigation from OUH to KW with open MRI images and three dimensional images overlay. In order to satisfy these functions of the three phases and optimize running cost and functionality, the survey were made and the results were summarized as functional requirements. By using scalable bandwidths control, the optimum bandwidths in each phase were decided. The data obtained indicate functional requirements for telesurgical operations and will provide the basis for future challenging tele-robotic surgery which is under developing in our project between OUH and KH.
