Application of XML Compressor [EXI] in Medical Image Database (DICOM)

Abstract: Recently, many healthcare organizations are planning to adopt Cloud Web services for storing and transmitting of medical information. SOAP (Simple Object Access Protocol) is the basic communication protocol of Cloud Web services, completely based on XML (eXtensible Markup Language) as an encoding language. The XML is a format that is widely used as a tool for data exchange and storage, but XML files are verbose in nature which means that the amount of information has to be stored, transmitted, and queried is often larger than that of other data formats. This huge size introduces bandwidth communication overhead, end to end communication delay, increased processing time and increased storage space. In this paper, we have presented an effective model to compress and to reconstruct digital imaging and communications in medicine (DICOM) images by using EXI compressor. The experimental results proved that the performance of the proposed technique shows better results than any other XML compression standards.
