An image display method for portable medical endoscopes using intelligent mobile devices / 国际生物医学工程杂志

ABSTRACT

Objective To study an image display method for portable medical endoscopes using intelligent mobile devices for solving the problem of lacking medical resources in remote areas and carrying inconvenience of endoscopic workstations.Method An high-definition camera was employed for image data acquisition,which was driven by the built-in Video4Linux drive program of a embedded Linux system.A wireless network card was used to establish a point-to-point network,and to build the LAN server.The mobile devices could acquire the collected image data through accessing the local area network,which could realize the real-time display on the LCD screen.Results The resolution of a collected image was 1 024×768 pixels,the bit depth was 24 bits,the frame rate was 30 frame/s,and the actual average transmission speed was about 2 MB/s.Conclusions The proposed method is effective and feasible.The collected image is clear,and the system has advantages of simple structure,low cost and easy to carry,which can save the manufacturing cost and meet the conditions of usage in remote areas.
