Abstract
Nowadays, Digital Imaging and Communications in Medicine (DICOM), an international standard used worldwide to access and handle various medical images through Picture Archiving and Communication System (PACS). This helps eliminate completely the use of costly and harmful traditional films. Besides, the existing infrastructures of the Internet have allowed us to develop the telemedicine services. However, the usage of foreign PACS is not suitable to diagnosis and medical consultation over the distance in Vietnam. This paper researches to implement PACS, online medical video consultation system and security DICOM Web Viewer serving diagnosis in Vietnam. First, we mention our methods of implementation. Then we discuss the results of completing image compression technology, connection technology, load balance technology for manufacturing PACS and online medical video consultation system. Next, the result of designing DICOM Web Viewer is introduced and updated. In order to solving security issue over Internet, modern security techniques are integrated into software system. Specially, by exploiting different techniques of data encoding, cryptography and watermarking, we propose an efficient solution to enhance information security in DICOM images over the Internet. Finally, our completed system has also been implemented and evaluated in hospitals.
