The Design And Implementation Of Telemedicine System

As all important part of telemedicine, Telemedicine consultation is a developing application of clinical medicine where information is transferred by the multimedia communication technology. Telemedicine is mainly used in areas of medical and public health database retrieval, telemedicine consultation and outpatient consultation, tele-medicine, tele-examination, remote monitoring, remote learning and remotemanagement of the iatrical incidents. During recent years, the developments of network technology and multimedia technology accelerate the conrse of integration, digital andintelligent ofthe communications technology.Based on the above background, the study analyzes the status at home and abroad. In the past, the communication of telemedicine was generally implemented by video conferencing systems which transmit patient information and diagnostic images through video. However, the images' quality can not be guaranteed, and it lacks strict supervision as well. to improve the situationg, my study will focus on the communication technology used in telemedicine consultation System and apply it to the telemedicine system devoloped by General Hospital of Shandong People' s Armed Police Forces, details are as follows.The innovated system in my report is designed to comprise two modules : data transmission module and medical video consultation module separately using different protocol for transmission. Medical data transmission module using DICOM protocol is a new network model of DICOM standards, which compromised the advantages of transfer process, the characteristics of hierarchy and the TCP / IP network protocol layer structure. Medical video consultation module implements multimedia data transmission via RTP / RTCP and IPv6 protocol, and achieves optimization through its RSVP protocol.Client and server-side bottom adopt the design of the thread pool, which can adjust the hardware configuration of nodes, synchronously regulating the number of requests received communications ceiling, SO as to achieve the best possible load balancing, play each node optimal performance.
