## Function Documentation

## ◆ dcmFindKeywordOfUID()

DCMTK_DCMDATA_EXPORT const char * dcmFindKeywordOfUID | ( | const char * | uid,
|  | const char * | defaultValue = NULL )

return the keyword of a UID.

Performs a table lookup and returns a pointer to a read-only string.

Parameters

  uid | UID string for which the keyword is to be looked up
  defaultValue | default to return if UID not known

Returns
  keyword string or defaultValue if UID is unknown

## ◆ dcmFindNameOfUID()

DCMTK_DCMDATA_EXPORT const char * dcmFindNameOfUID | ( | const char * | uid,
|  | const char * | defaultValue = NULL )

return the name of a UID.

Performs a table lookup and returns a pointer to a read-only string.

Parameters

  uid | UID string for which the name is to be looked up
  defaultValue | default to return if UID not known

Returns
  name string or defaultValue if UID is unknown

## ◆ dcmFindUIDFromKeyword()

DCMTK_DCMDATA_EXPORT const char * dcmFindUIDFromKeyword | ( | const char * | keyword | ) |

return the UID of a keyword.

Performs a table lookup and returns a pointer to a read-only string.

Parameters

  keyword | keyword string for which the corresponding UID is to be looked up

Returns
  UID string or NULL if keyword is unknown

## ◆ dcmFindUIDFromName()

DCMTK_DCMDATA_EXPORT const char * dcmFindUIDFromName | ( | const char * | name | ) |

return the UID of a name.

Performs a table lookup and returns a pointer to a read-only string.

Parameters

  name | name string for which the corresponding UID is to be looked up

Returns
  UID string or NULL if name is unknown

## ◆ dcmGenerateUniqueIdentifier()

DCMTK_DCMDATA_EXPORT char * dcmGenerateUniqueIdentifier | ( | char * | uid,
|  | const char * | prefix = NULL )

creates a Unique Identifier in uid and returns uid.

uid must be at least 65 bytes. Care is taken to make sure that the generated UID is 64 characters or less. If a prefix string is not passed as the second argument a default of SITE_INSTANCE_UID_ROOT (see below) will be used. Otherwise the supplied prefix string will appear at the beginning of uid. The UID is created by appending to the prefix the following:

- the host ID (if obtainable, zero otherwise),
- the process ID (if obtainable, zero otherwise),
- the system calendar time, and
- an accumulating counter for this process.
  Parameters

    uid | pointer to buffer of 65 or more characters in which the UID is returned
    prefix | prefix for UID creation

  Returns
    pointer to UID, identical to uid parameter

## ◆ dcmGetPropertiesOfUID()

returns true if the uid is one of the Storage SOP Classes.

Performs a table lookup in the dcmAllStorageSOPClassUIDs, dcmImageSOPClassUIDs and/or other tables depending on the requested type of Storage SOP Class. Please note that, by default, this function only covers those Storage SOP Classes that fit into the conventional PATIENT-STUDY-SERIES-INSTANCE information model, i.e. non-patient DICOM objects are missing. This can be changed by setting the optional type parameter to ESSC_NonPatient.

Parameters

  uid | UID string
  type | type of Storage SOP Class (default: patient objects only)

Returns
  true if UID is a known Storage SOP Class, false otherwise

## ◆ dcmIsImageStorageSOPClassUID()

DCMTK_DCMDATA_EXPORT OFBool dcmIsImageStorageSOPClassUID | ( | const char * | uid | ) |

returns true if the uid is one of the Image Storage SOP Classes.

This is just a shortcut for dcmIsaStorageSOPClassUID(uid, ESSC_Image).

Parameters

  uid | UID string

Returns
  true if UID is a known Image Storage SOP Class, false otherwise

## ◆ dcmSOPClassUIDToModality()

DCMTK_DCMDATA_EXPORT const char * dcmSOPClassUIDToModality | ( | const char * | sopClassUID,
|  | const char * | defaultValue = NULL )

performs a table lookup and returns a short modality identifier that can be used for building file names etc.

Identifiers are defined for all storage SOP classes. Returns 'defaultValue' if no modality identifier found or sopClassUID==NULL.

Parameters

  sopClassUID | UID string
  defaultValue | default to return if UID not known

Returns
  modality string for modality UID, or defaultValue if not found

## Variable Documentation

## ◆ dcmAllStorageSOPClassUIDs

DCMTK_DCMDATA_EXPORT const char* dcmAllStorageSOPClassUIDs[]
| extern

an array of const strings containing all known Storage SOP Classes that fit into the conventional PATIENT-STUDY-SERIES-INSTANCE information model, i.e.

everything a Storage SCP might want to store in a PACS. Special cases such as Hanging Protocol or Color Palette Storage SOP Class are not included in this list. WARNING: This list contains more than 64 entries, i.e. it is not possible to use this list to configure the association negotiation behavior of a Storage SCU that always proposes two presentation contexts for each SOP class.

## ◆ dcmImageSOPClassUIDs

DCMTK_DCMDATA_EXPORT const char* dcmImageSOPClassUIDs[]
| extern

a global constant array of string pointers containing the UIDs of all known Image SOP Classes.

The global variable numberOfDcmImageSOPClassUIDs defines the size of the array. NOTE: this list represents a subset of the dcmAllStorageSOPClassUIDs list

## ◆ dcmLongSCUStorageSOPClassUIDs

DCMTK_DCMDATA_EXPORT const char* dcmLongSCUStorageSOPClassUIDs[]
| extern

an array of const strings containing all storage SOP classes that are proposed by default by those Storage SCU components in DCMTK that always propose one presentation context for each SOP class, e.g.

movescu or dcmqrdb. This list is guaranteed to have at most 120 entries (to leave room for FIND/MOVE presentation contexts).

Referenced by dcmGetPropertiesOfUID().

## ◆ dcmShortSCUStorageSOPClassUIDs

DCMTK_DCMDATA_EXPORT const char* dcmShortSCUStorageSOPClassUIDs[]
| extern

an array of const strings containing all storage SOP classes that are proposed by default by those Storage SCU components in DCMTK that always propose TWO presentation context for each SOP class, e.g.

storescu. This list is guaranteed to have at most 64 entries.
