Detailed Description

Class representing an object of the "Segmentation SOP Class".

Constructor & Destructor Documentation

◆ DcmSegmentation()

DcmSegmentation::DcmSegmentation ( )

protected

Protected default constructor.

Library users should the factory create..() method in order to create an object from scratch

Member Function Documentation

◆ addForAllFrames()

virtual OFCondition DcmSegmentation::addForAllFrames ( const FGBase & group )

virtual

Add a functional group for all frames.

Parameters

group The group to be added as shared functional group. The

Returns: EC_Normal if adding was successful, error otherwise

◆ addFrame() [1/2]

virtual OFCondition DcmSegmentation::addFrame ( Uint8 * pixData )

protectedvirtual

Add frame to segmentation object.

Parameters

pixData Pixel data to be added. Length must be rows*columns bytes. Pixel data is copied so it must be freed by the caller.

Returns: EC_Normal if adding was successful, error otherwise

◆ addFrame() [2/2]

virtual OFCondition DcmSegmentation::addFrame	(	Uint8 *	pixData,
		const Uint16	segmentNumber,
		const OFVector< FGBase * > &	perFrameInformation
	)

virtual

Add frame to segmentation object.

Parameters

pixData	Pixel data to be added. Length must be rows*columns bytes. For binary segmentations (bit depth i.e. Bits Allocated/Stored=1), each byte equal to 0 will be interpreted as "not set", while every other value is interpreted as "set". For fractional segmentations the full byte is copied as is.
segmentNumber	The logical segment number (>=1) this frame refers to. The segment identified by the segmentNumber must already exist.
perFrameInformation	The functional groups that identify this frame (i.e. which are planned to be not common for all other frames). The functional groups are copied, so ownership of each group stays with the caller no matter what the method returns.

Returns: EC_Normal if adding was successful, error otherwise

◆ addSegment()

virtual OFCondition DcmSegmentation::addSegment	(	DcmSegment *	seg,
		Uint16 &	segmentNumber
	)

virtual

Add segment to segmentation object.

Parameters

seg	The segment that should be added
segmentNumber	The logical segment number that was assigned for this segment. Contains 0 if adding failed.

Returns: EC_Normal if adding was successful, error otherwise

◆ check()

virtual OFBool DcmSegmentation::check ( const OFBool checkFGStructure = OFTrue )

virtual

Perform some basic checking.

This method is also invoked when writing the object to a DICOM dataset or file.

Parameters

checkFGStructure If OFTrue (default), structure of functional groups is checked, too.

Returns: OFTrue, if no errors were found, OFFalse otherwise.

◆ checkPixDataLength()

OFBool DcmSegmentation::checkPixDataLength	(	DcmElement *	pixelData,
		const Uint16	rows,
		const Uint16	cols,
		const Uint16 &	numberOfFrames
	)

private

Check the length of the pixel data.

Parameters

pixelData	The Pixel Data element
rows	Number of rows
cols	Number of columns
numberOfFrames	Number of frames

Returns: OFTrue if length is valid, OFFalse otherwise

◆ concatFrames()

virtual void DcmSegmentation::concatFrames	(	OFVector< DcmIODTypes::Frame * >	frames,
		Uint8 *	pixData,
		const size_t	bitsPerFrame
	)

protectedvirtual

This is the counterpart to the extractFrames() function.

It takes a number of frames that are in binary segmentation format (i.e. "bit-packed") and concatenates them together so the resulting memory block fits the Pixel Data format for binary segmentations. Thus method ensure that frames are aligned bit for bit concatenated to each other with only (if applicable) having unused bits after the last frame.

Parameters

frames	The source frames
pixData	The pixel data element data to be filled. Size must be at least bitsPerFrame * number of frames.
bitsPerFrame	Bits required per frame, usually rows * columns

equipmentInfo	Equipment that is responsible for creating the segmentation. All attributes in equipmentInfo must have non-empty values.

◆ importFromSourceImage() [1/2]

virtual OFCondition DcmSegmentation::importFromSourceImage	(	const OFString &	filename,

	)

virtual

Import Patient, Study, and Frame of Reference level information from the given item.

The method does only import Frame of Reference if Frame of Reference UID is found in the image (and no error is reported if not). The reason is that if the source images of the segmentation do have an FoR, the segmentation object must have the same one, so we must import it. If the images do not have an FoR, we must not try at all importing it. The current content of this object is not deleted before reading. If the log stream is set and valid the, the reason for any error might be obtained from the error/warning output.

Parameters

filename	Reference to DICOM dataset from which the document should be read
takeOverCharset	If OFTrue (default), Specific Character Set is taken over from imported dataset. If it's not present or empty (invalid), the attribute will not be present in this class either.

Returns: EC_Normal if successful, an error code otherwise

◆ importFromSourceImage() [2/2]

virtual OFCondition DcmSegmentation::importFromSourceImage	(	DcmItem &	dataset,
		const OFBool	takeOverCharset = `OFTrue`
	)

virtual

Import Patient, Study, and Frame of Reference level information from the given item.

The method does only import Frame of Reference if Frame of Reference (FoR) UID is found in the image (and no error is reported if not). The reason is that if the source images of the segmentation do have an FoR, the segmentation object must have the same one, so we must import it. If the images do not have an FoR, we must not try at all importing it. If the log stream is set and valid the, the reason for any error might be obtained from the error/warning output.

Parameters

dataset	Reference to DICOM dataset from which the document should be read
takeOverCharset	If OFTrue (default), Specific Character Set is taken over from imported dataset. If it's not present or empty (invalid), the attribute will not be present in this class either.

◆ setCheckFGOnWrite()

virtual void DcmSegmentation::setCheckFGOnWrite ( const OFBool doCheck )

virtual

If enabled, functional group structure is checked before actual writing is performed in the write() method.

Checking might be time consuming on functional groups with many frames, though disabling might result in invalid functional group structures. Disabling should only be done if the user knows that the functional groups are valid, wants to to adapt the functional groups manually after calling write() or knows what he's doing otherwise.
Per default, checking is enabled.

Parameters

doCheck If OFTrue, checking will be performed. If OFFalse, no checks are performed.

◆ setContentIdentification()

virtual OFCondition DcmSegmentation::setContentIdentification	(	const ContentIdentificationMacro &	contentIdentification,
		const OFBool	checkValue = `OFTrue`
	)

virtual

Set content identification info for this segmentation object.

Parameters

contentIdentification	The content identification of this segmentation
checkValue	If OFTrue, the data provided is checked for validity (as possible)

Returns: EC_Normal if content identification could be set correctly, OFFalse otherwise

◆ setEquipmentInfo()

virtual OFCondition DcmSegmentation::setEquipmentInfo	(	const IODGeneralEquipmentModule::EquipmentInfo &	equipmentInfo,
		const OFBool	checkValue = `OFTrue`
	)

virtual

Set equipment info for this segmentation object.

Parameters

equipmentInfo	The description of the equipment used to create this segmentation
checkValue	If OFTrue, the data provided is checked for validity

Returns: EC_Normal if equipment information could be set successfully, error otherwise

◆ setLossyImageCompressionFlag()

virtual OFCondition DcmSegmentation::setLossyImageCompressionFlag	(	const OFString &	ratios,
		const OFString &	methods,
		const OFBool	checkValues = `OFTrue`
	)

virtual

Set lossy compression flag of the segmentation object to "01".

If one of the source images of this segmentation has undergone lossy compression then this function should be called.

Parameters

ratios	Compression ratios (separated by backslash) of the applied lossy compression steps. Only one value (and no backslash) if only one step was performed.
methods	Methods (separated by backslash) of the applied lossy compression steps. Only one value (and no backslash) if only one step was performed.
checkValues	If OFTrue, the data provided is checked for validity

Returns: EC_Normal if lossy compression info could be set, error code otherwise

Returns: EC_Normal if writing was successful, error otherwise

◆ writeConcatenation()
