The innovative aspect of it is the fundametal role of ICC in reconciling DICOM with TIFF and therefore with XHTML too. PDI HYBRID FILES adopts a design which reduces technological dependences and concentrates on DICOM, TIFF, ICC and XHTML as the basics of medical image distribution on portable media. A careful study of the conformance of these browsers to ICC standard is made and guides the design of the ICC profiles included into the hybrid dicom tiff files. Safari and Firefox are followed by Internet Explorer in implementing this technology. PDI HYBRID FILES rely on ICC color management in order to represent correctly 16 bit-depth (and also 10- 12- 14- bit depth) dicom tiff image. The one and same file is seen from a DICOM viewer and from the web browser, not a transformed copy of it. In our case, a dicom tiff file is tiff, is a natural format for XHTML and therefore can be accessed directly from the browser, without transformation by means of any specialized application. The media content can be accessed from two "entry points" on the media: the DICOMDIR file for DICOM imaging information and optionally the INDEX.HTM.
Hybrid dicom-tiff16 contains the original dicom data referred to by dicom and by tiff metadata and therefore is diagnostic quality. Between others: - The intent is that the media content be a “complete set of images of diagnostic quality”. In comparison to dicom standard CD, IHE PDI adds constraints and features. To do so, we built a storeSCP dicom node which transforms received dicom files into dicom-tiff16 files stored within a filesystem with DICOMDIR and INDEX.HTM access points, ready for compliant CD burning. We go one step further and demonstrate now that the perfect use case for such files is the creation of dicom image CDs conformant to IHE "Portable Data for Imaging" profile. At RSNA 2008, we demonstrated how to create hybrid dicom tiff16 icc files (Abstract ID: 6014334).
