## Detailed Description

Class representing the Multi-Frame Dimension Module:

Dimension Organization Sequence: (SQ, VM 1-n, Type 1)

> Dimension Organization UID: (UI, 1, 1) Dimension Organization Type: (CS, 1, 1) Dimension Index Sequence: (SQ, 1-n, 1) Dimension Index Pointer (AT, 1, 1) Dimension Index Private Creator (LO, 1, 1C) Functional Group Pointer (AT, 1, 1C) Functional Group Private Creator (LO, 1, 1C) Dimension Organization UID (UI, 1, 1C) Dimension Description Label (LO, 1, 3)

The Dimension Organization UIDs within the Dimension Organization Sequence cannot be set explicitly. Instead the sequence is populated from the data found within the Dimension Index Sequence.

## Constructor & Destructor Documentation

## ◆ IODMultiframeDimensionModule()

IODMultiframeDimensionModule::IODMultiframeDimensionModule | ( | OFshared_ptr< DcmItem > | item,
|  | OFshared_ptr< IODRules > | rules )

Constructor.

Parameters

  item | The item to be used for data storage. If NULL, the class creates an empty data container.
  rules | The rule set for this class. If NULL, the class creates one from scratch and adds its values.

## Member Function Documentation

## ◆ addDimensionIndex()

virtual OFCondition IODMultiframeDimensionModule::addDimensionIndex | ( | const DcmTagKey & | dimensionIndexPointer,
|  | const OFString & | dimensionOrganizationUID,
|  | const DcmTagKey & | functionalGroupPointer,
|  | const OFString & | dimensionDescriptionLabel = "",
|  | const OFString & | dimensionIndexPrivateCreator = "",
|  | const OFString & | functionalGroupPrivateCreator = "" )
| virtual

Convenience method to add Dimension Index.

Parameters

  dimensionIndexPointer | The Dimension Index Pointer attribute
  dimensionOrganizationUID | The Dimension Organization UID of the dimension organization the pointer refers to. If UID does not exist yet (in the Dimension Organization Sequence, it is created there automatically).
  functionalGroupPointer | The functional group where the pointer attribute can be found
  dimensionDescriptionLabel | The description label of this dimension (optional)
  dimensionIndexPrivateCreator | The private creator of the Dimension Index Pointer attribute. Required if dimensionIndexPointer points to a private attribute tag.
  functionalGroupPrivateCreator | The private creator of the functional group. Required if functionalGroupPointer points to a private attribute tag.

Returns
  EC_Normal if index could be added, error otherwise (basic parameter checking)

## ◆ checkDimensions()

virtual OFCondition IODMultiframeDimensionModule::checkDimensions | ( | DcmItem * | fgItem = NULL | ) |
| virtual

Check dimensions for consistency with functional groups.

Note that one can provide an item that provides the dataset containing the functional groups to check against. This item must contain on main level the Shared and Per-frame Functional Group Sequence. If no item is given (NULL pointer) it is tried to find these sequences within "this" object which works in the case that this class was initialized with an existing item (or the fg data was inserted in another way afterwards).

Parameters

  fgItem | The item containing functional group information

Returns
  EC_Normal, if consistency is fine, error otherwise

## ◆ clearData()

virtual void IODMultiframeDimensionModule::clearData | ( |  | ) |
| virtual

Clear (removes) all attributes handled by the modules of this component.

Rules are not reset.

## ◆ getCheckOnWrite()

virtual OFBool IODMultiframeDimensionModule::getCheckOnWrite | ( |  | ) |
| virtual

Returns whether checkDimensions() routine is called when writing the module.

Returns
  OFTrue if calling of checkDimensions() is enabled when writing, OFFalse otherwise.

## ◆ getDimensionIndexSequence()

virtual OFVector< DimensionIndexItem * > & IODMultiframeDimensionModule::getDimensionIndexSequence | ( |  | ) |
| virtual

Get content of the Dimension Index Sequence.

Returns
  Reference to the Dimension Index Pointer Sequence

## ◆ getDimensionOrganizationSequence()

virtual OFVector< DimensionOrganizationItem * > & IODMultiframeDimensionModule::getDimensionOrganizationSequence | ( |  | ) |
| virtual

Get content of the Dimension Organization Sequence.

Returns
  Reference to the Dimension Organization Sequence

## ◆ getDimensionOrganizationType()

virtual OFCondition IODMultiframeDimensionModule::getDimensionOrganizationType | ( | OFString & | value,
|  | const signed long | pos = 0 ) const
| virtual

Get Dimension Organization Type.

Parameters

  value | Reference to variable in which the value should be stored
  pos | Index of the value to get (0..vm-1), -1 for all components

Returns
  EC_Normal if successful, an error code otherwise

## ◆ getIndexElement()

virtual DcmElement * IODMultiframeDimensionModule::getIndexElement | ( | DcmSequenceOfItems * | perFrameFG,
|  | const DcmTagKey & | fgPointer,
|  | const DcmTagKey & | indexPointer,
|  | const OFString & | fgPrivateCreator,
|  | const OFString & | privateCreator )
| virtual

Get specific index pointer element from per-frame functional group sequence.

Prints out error messages if index does not exist or index location information provided by parameters is incomplete or invalid

Parameters

  perFrameFG | An instance of the Per-Frame Functional Group Sequence that should be searched
  fgPointer | The tag key of the functional group the value resides in
  indexPointer | The tag of the dimension value inside the functional group
  fgPrivateCreator | The private creator of the fgPointer tag key. Only required if fgPointer is a private tag key (odd element number)
  privateCreator | The private creator of the indexPointer tag key. Only required if indexPointer is a private tag key (odd element number)

Returns
  The element pointed to. If element could not be located, NULL is returned.

## ◆ getName()

virtual OFString IODMultiframeDimensionModule::getName | ( |  | ) | const
| virtual

Get name of module ("MultiframeDimensionModule")

Returns
  Name of the module ("MultiframeDimensionModule")

Implements IODComponent.

## ◆ read()

virtual OFCondition IODMultiframeDimensionModule::read | ( | DcmItem & | source,
|  | const OFBool | clearOldData = OFTrue )
| virtual

Read data into this module from given item.

Parameters

  source | The item to read from
  clearOldData | If OFTrue, old data in this module is cleared first (default: OFTrue)

Returns
  EC_Normal if reading was successful, error otherwise

Reimplemented from IODComponent.

## ◆ setCheckOnWrite()

virtual void IODMultiframeDimensionModule::setCheckOnWrite | ( | const OFBool | doCheck | ) |
| virtual

Enable or disable calling of the checkDimensions() routine when writing the module.

Checking can be very time-consuming if many frames are present. Default is OFTrue.

Parameters

  doCheck | If enabled, checkDimensions() is called when writing.

## ◆ setDimensionOrganizationType()

virtual OFCondition IODMultiframeDimensionModule::setDimensionOrganizationType | ( | const OFString & | value,
|  | const OFBool | checkValue = OFTrue )
| virtual

Set Dimension Organization Type (Defined Terms as of DICOM 2014a "3D" and "3D_TEMPORAL")

Parameters

  value | Value to be set (single value only) or "" for no value
  checkValue | Check 'value' for conformance with VR and VM if enabled

Returns
  status EC_Normal if successful, an error code otherwise

## ◆ write()

Write this module to given item.

Parameters

  destination | The item to write to

Returns
  EC_Normal if writing was successful, error otherwise

Reimplemented from IODComponent.

## Member Data Documentation

## ◆ m_CheckOnWrite

OFBool IODMultiframeDimensionModule::m_CheckOnWrite
| private

If enabled, dimension structures are checked when writing the module.

This can be very time-consuming if many frames are present. Default is OFTrue.
