Mixed image format environments: comparisons, tradeoffs, and issues

As the extent of the networked image environments grows, it becomes increasing likely that multiple image formats will be present within a network. This paper addresses the general evolution of this environment through a specific examination of three image formats likely to be present: Digital Image Communication in Medicine (DICOM) Image Processing and Interchange (IPI)-Image Interchange Format (IIF) and the National Image Transmission Format (NITF). For each format, its approach to image format development and data encapsulation are both presented and compared to the other formats, and distinguishing capabilities and limitations are identified. A possible integration scheme for IIF and DICOM is presented and the relationship of NITF to IPI-IIF and DICOM is identified. Since a mixed image format environment could include acquired imagery, reference imagery material, or even document imagery, generalized interoperability will be a requirement of future systems. Results are generalized to provide an indication as to how this problem may be addressed
