DICOM (Digital Imaging and Communication in Medicine) is a message that uses a network to connect devices with different types of visual information for the first time at the 1992 Radiological Society of North America (RSNA) conference. It is a protocol about transmission.

PACS system (Picture Archiving Communication System) acquires medical images, especially radiological diagnosis images in digital form, and then transmits them through high speed network. Medical images are used instead of past X-ray film. Because it is stored as digital data, it is a comprehensive digital image management system and transmission system for radiologists and clinicians to treat patients using an image retrieval device instead of a conventional film view box. PACS includes image display and processing, data communication and networking, database, information management, user interface, data storage and management. and management technologies are comprehensively established.

The patent invention is a system for capturing DICOM medical images from a PACS terminal and transmitting them to a terminal through a communication network. Therefore, the DICOM medical image may be deteriorated during the capture process, and a problem such as a transmission speed of a large media file may occur due to the communication means used.

Accordingly, it is desirable to develop a UPnP-based medical image delivery system suitable for media file sharing and data sharing such as images. UPnP (Universal Plug & Play) is a communication protocol that allows media such as video to be shared by a communication means in an electronic device.
