Virtual Microscopy System Based On B/S Model

Traditional light microscope technology has been developed for almost three hundred years. As the fast progress of computer technology and digital image process method, a brand new microscopic technology called virtual microscope emerged. To provide remote slide browsing service, all of these early systems are built up in client/server architecture.With the mobile internet and heterogeneous architected mobile computing platform expending, now the defects of old virtual microscopic system based on client/server model become more and more apparent, such as: you have to develop clients for each different terminal platform; deployment, management and update of system turns to be too complex even to handle; communication protocols dramatically differ between heterogeneous -architected platforms; etc.To tackle with all these problems, we propose and implement a browser/server architecture based virtual microscopic system. Its server end is developed on ASP.NET framework using C# programming language applying distributed microscopic image storage solution. Its browser end is coded in JavaScript language while utilizing Ajax tech to achieve asynchronous image data obtaining. Communication between server and browser employs standard http protocol to overcome the difference of heterogeneous platforms. The prototype of this system so far now is able to properly works.The whole system could be divided into four modules: server-end business logic module, database module, distributed image file storage module and browser client module. To offer remote real-time microscopic image browsing service, the following functions have been accomplished: movement of microscopic visual field, zoom in and out, position by coordinates, slide comment etc. Thanks to the B/S architecture, the problems exits on the traditional C/S architected virtual microscopic system such as terminal platform support, deployment and management complexity are no longer bothering.As it's been tested, the built up prototype system could run stably and reliably while providing excellent accessibility. The objective of this project is to meet the demand of public accessible virtual microscopic service by designing and realizing a feasible, self-developed solution.
