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.

Note:

In Oracle Database 10g Release 2 (10.2), Oracle Multimedia DICOM introduced these encoding rules to support metadata extraction and image content processing only. In Oracle Database 11g Release 1 (11.1), Oracle Multimedia DICOM provided full support for medical imaging.

This appendix includes these sections:

C.1 Transfer Syntax for Medical Imaging

Table C-1 lists the DICOM encoding rules that support medical imaging in Oracle Multimedia DICOM. See Section C.2 for descriptions of the abbreviations used in the Support column for Table C-1.

C.2 Definitions for Transfer Syntax Abbreviations

These abbreviations are used in Table C-1:

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.

* (the asterisk character)

This encoding rule requires the Java Advanced Imaging (JAI) Image I/O Tools provided by Oracle.
