GE Medical Systems SIGNA PROFILE CONFORMANCE STATEMENT
REV 2.7 sm 2303347
doc ver 2.7 44
This Application Profile facilitates the interchange of primary CT and MR images as well as processed CT
and MR images as Secondary Capture and Standalone Overlay Images. Please refer to appendix A for the
IOD definitions. CT, MR, SC and OV images may co-exist within the same File-set.
Typical interchanges would be between acquisition devices, archives and workstations within and between
institutions.
3.3.2.1 Roles and Service Class Options
This Application Profile Class uses the Media Storage Service Class defined in PS3.4 with the Interchange
Option.
The Application Entity shall support one or more roles of the File-set Creator, File-set Reader and File-set
Updater defined in PS3.10.
3.3.2.1.1 File Set Creator
The Application Entity acting as a File-set Creator generates a File Set under the PRI-CTMR-MOD12
Application Profile Class. Typical entities using this role would include CT or MR equipment and archive
systems which generate a patient record to transfer to another institution. File Set Creator shall be able to
generate the Basic Directory SOP Class in the DICOMDIR File with all types of Directory Records related to
the SOP Classes stored in the File-set.
FSC for the MOD profile has no concept of finalizing the disc at the completion of most recent write session.
This is a requirement of CD-R and does not apply to the MOD profiles.
3.3.2.1.2 File Set Reader
The role of File Set Reader is used by the Application Entities which receive a transferred File Set. Typical
entities using this role would include display workstations and archive systems which receive a patient
record transferred from another institution. File Set Readers shall be able to read all the SOP Classes defined
for the specific Application Profile for which a Conformance Statement is made using all the defined
Transfer Syntaxes.
3.3.2.1.3 File Set Updater
The role of File Set Updater is used by Application Entities which receive a transferred File Set and update
it by the addition of information. Typical entities using this role would include analytic workstations which
for instance may add to the File-set an information object containing a processed (e.g., edge-enhanced)
image. File-set Updaters do not have to read the images. File-set Updaters shall be able to generate one or
more of the SOP Instances defined for the specific Application Profile for which a conformance statement is
made and to read and update the DICOMDIR file.
3.3.3 Standard Application Profiles
The MOD Archive Server supports the standard Application Profile: CTMR-MOD as an FSC, FSR or FSU.
