Abstract:

Compared with traditional PACS that are based on DICOM networks, distributed PACS improve themselves in system architecture and performance. However,  the speciality and complexity of the DICOM standard prevent the improvements in the performance of distributed PACS. DICOM image access services shield  the complexity of the DICOM communication protocol and data structure in thc bottom layer, and provide a series of IDL interfaces and access mechanisms  for the upper-layer services and other applications in distributed PACS so that they can access all kinds of data in DICOM image files. DICOM image acce  ss services not only make PACS more open than before, but also improve the interconnectivity and interoperability of PACS.

Key words: distributed PACS, DICOMI image access service
