I DICOM Encoding Rules

Digital Imaging and Communications in Medicine (DICOM) includes a complete set of encoding rules for medical images. These encoding rules are also called transfer syntax. Oracle interMedia ("interMedia") provides DICOM encoding rules that support metadata extraction and image content processing.

Table I-1 lists the DICOM encoding rules supported by Oracle interMedia.

The following abbreviations are used in Table I-1.

M = Metadata extraction support is provided for the getDicomMetadata( ) and setProperties( ) methods.
I = Image content support is provided for the processCopy( ) and setProperties( ) methods.
N = Not supported by interMedia.
