C DICOM Encoding Rules

Digital Imaging and Communications in Medicine (DICOM) includes transfer syntax. The transfer syntax is a complete set of DICOM encoding rules for medical images. In Oracle Database 10g Release 2, Oracle Multimedia DICOM introduced these encoding rules to support metadata extraction and image content processing only (see Oracle Multimedia Reference). In Oracle Database 11g Release 1 (11.1), Oracle Multimedia DICOM provides full support for medical imaging.

Table C-1 lists the DICOM encoding rules that support medical imaging in Oracle Multimedia DICOM.

Note:

The symbols in the Support column are defined in the table that follows Table C-1.

These abbreviations are used in Table C-1:

Symbol	Definition
P	The processCopy( ), createDicomImage( ), and writeMetadata( ) procedures and methods are able to produce DICOM content of this transfer syntax.
R	The extractMetadata( ), setProperties( ), and isConformanceValid( ) methods are able to read DICOM content of this transfer syntax. If the encoding rule is not changing between the source and destination DICOM content, then the processCopy( ), createDicomImage( ), and writeMetadata( ) procedures and methods are also supported for this transfer syntax.
*	This encoding rule requires the Java Advanced Imaging (JAI) Image I/O Tools provided by Sun Microsystems. For more information about JAI Image I/O Tools, see the Sun Microsystems Web site at `http://java.sun.com/` See also the following script, which is available in the Oracle home directory after installation: On Linux and UNIX: <ORACLE_HOME>/ord/im/admin/initjp2.sql On Windows: <ORACLE_HOME>\ord\im\admin\initjp2.sql
-	No support (for P or R) is provided.
