F.8.1.1 STORAGE-SCP AE Element Use

The following Elements of Composite SOP Instances received by the STORAGE-SCP AE are either stored to the permanent EXAMPLE-QUERY-RETRIEVE-SERVER database or of particular importance in the received images.

SOP Instances conforming to the following Composite Image SOP Classes are fully supported for display on the system workstations.

Patient

Patient Name

(0010,0010)

Opt

STORAGE-SCP AE can be configured to apply a default value if there is no value specified.

Value is saved to database as separate first and last names. Only first and last names are entered in the EXAMPLE-QUERY-RETRIEVE-SERVER database. Both first and last names can be a maximum of 64 characters each.

Names will be parsed correctly if they are in the format of 'lname^fname' or 'lname, fname'. If space separation is used (i.e., 'lname fname') then the entire name will be treated as the last name.

Patient ID

(0010,0020)

Opt

STORAGE-SCP AE can be configured to apply a default value if there is no value specified.

Verification on incoming Patient IDs is performed. If an ID already exists but the existing name does not match, then the ID is coerced because different Patient records in the EXAMPLE-QUERY-RETRIEVE-SERVER database cannot have identical Patient IDs.

Value is saved to database.

Patient's Birth Date

(0010,0030)

Opt

STORAGE-SCP AE can be configured to apply a default value if there is no value specified.

Value is saved to database.

Patient's Sex

(0010,0040)

Opt

First character must be 'M', 'm', 'F', 'f', 'O', or 'o'. If a different value, or not specified, then will be entered in the database as 'U', unknown. Value is saved to database. 'U' is never exported in DICOM images; instead, the Element value will be left empty for export.

Value is saved to database.

Accession Number

(0008,0050)

Opt

STORAGE-SCP AE can be configured to apply a default value if there is no value specified. Matching used to determine which Accession number to apply is configurable (i.e., HIS/RIS provided Accession Number may be used if the Patient ID, Patient Name, Study Date, and Modality provided in the HIS/RIS and SOP Instance match).

Value is saved to database.

Opt

Value is saved to database.

Body Part Examined

(0018,0015)

Opt

If matched value(s) in the EXAMPLE-QUERY-RETRIEVE-SERVER exam type database then it will be saved to the database as an exam type.

General Image

Image Type

(0008,0008)

Opt

If the third value, the modality specific value, matches value(s) in the EXAMPLE-QUERY-RETRIEVE-SERVER exam type database then it will be saved to the database as an exam type.

Cond

The following photometric interpretations are supported for image display purposes:

MONOCHROME1, MONOCHROME2, RGB,

PALETTE COLOR, YBR FULL 422, and YBR FULL.

Required if SOP Instance is an Image.

Bits Allocated

(0028,0100)

Cond

Must be 8 or 16 bits for image display purposes.

Required if SOP Instance is an Image.

Bits Stored

(0028,0101)

Cond

Number of Rows in Overlay.

Required in order to display an Overlay.

Overlay Columns

(6000,0011)

Cond

Number of Columns in Overlay.

Required in order to display an Overlay.

Overlay Type

(6000,0040)

Cond

Overlay data is used only if the value is "G", Graphics. Graphic overlay data can be automatically displayed if the system is configured to do so. "ROI", Region Of Interest, overlay data is not displayed to the user of the system.

SOP Common

SOP Instance UID

(0008,0018)

Mand

Must be provided. If a duplicate SOP Instance UID is received, the system can be configured to either coerce the duplicate value with a new UID or replace the original UID with the newly received one. The system can also be configured to either preserve the original UID or assign a new UID if the received image data is lossy compressed by the QUERY-RETRIEVE-SERVER prior to archival.


Note

Note that only overlay information contained in the 6000 Group will be used for display. Overlay information contained in the other possible Groups (6002, 6004, etc.) will be ignored for display purposes. Such information will still be archived however.

F.8.1.2 STORAGE-SCU AE Element Modification

The following table contains a list of all Elements that can have a value modified by the STORAGE-SCU at the time of export using the Storage Service depending on the capabilities of the receiver:

Module

Attribute Name

Tag ID

Value

Image Pixel

Photometric Interpretation

(0028,0004)

STORAGE-SCU AE can convert all images to MONOCHROME2 or RGB based on the configuration for the destination AE.

If the photometric interpretation of the image data is altered in a lossy manner, which could occur when converting from color to grayscale, then the SOP Instance UID is altered.

VOI LUT

Window Center

(0028,1050)

Default Window Center value can be configured for a specific destination AE.

Window Width

(0028,1051)

Default Window Width value can be configured for a specific external destination AE.

SOP Common

SOP Instance UID

(0008,0018)

System assigns a new UID if the image data is lossy compressed by the STORAGE-SCU AE at the time of export. Unless the pixel data is lossy compressed or there is a conflict between duplicate SOP Instance UIDs the original value received is not altered.
