In order to enhance the readability, extensibility and sharing of DICOM files, we have introduced XML into DICOM file
system (SPIE Volume 5748) and the multilayer tree structure into DICOM (SPIE Volume 6145). In this paper, we
proposed mapping DICOM to ODF(OpenDocument Format), for it is also based on XML. As a result, the new format
realizes the separation of content(including text content and image) and display style. Meanwhile, since OpenDocument
files take the format of a ZIP compressed archive, the new kind of DICOM files can benefit from ZIP's lossless
compression to reduce file size. Moreover, this open format can also guarantee long-term access to data without legal or
technical barriers, making medical images accessible to various fields.
