Function Documentation

◆ applyFrameSpecificOperation()

MLDICOM_TO_ML_TOOLS_EXPORT bool ml::DicomToMLTools::applyFrameSpecificOperation ( const VoxelDoubleOperations operationMode,
const SubImage srcSubImage,
SubImage dstSubImage,
const PositionSpecificDoubleVector positionDoubles,
const VoxelDoubleOperations  dummyOperationMode = Copy,
const MLdouble  dummyOperationValue = 0.0,
PositionSpecificDoubleVector valueFreePositions = nullptr,
bool  isOldMultiFrameDICOM = false 
)

Copy voxels from overlapping regions of srcSubImage to dstSubImage and apply
the operationMode if for the z, t, u position of the slice an entry can be found in positionDoubles whose double value can be used for modification.

The double operation is performed regardless of the voxel data type and whether it can store the result precision or not. If no such entry is found and the isOldMultiFrameDICOM mode is not executed as explained below then the dummyOperationMode and value are used.

Parameters
operationModeThe operation to be applied as transfer operation from srcSubImage voxels to dstSubImage voxels on slices where an entry in positionDoubles could be found.
srcSubImageThe source of the voxels to be processed and written into dstSubImage.
dstSubImageThe target for the voxels to be read from dstSubImage and then processed.
positionDoublesA set of double values associated to frame positions in z,t, and u.
dummyOperationModeThe operation to be applied as transfer operation from srcSubImage voxels to dstSubImage voxels on slices for which no entry in positionDoubles could be found.
dummyOperationValueThe double to be used as value in conjunction with dummOperationMode.
valueFreePositionsIf non nullptr: An array of z, t, and u positions for which no entries in doublePositions exist and for which the copy operation was performed. Ignored if nullptr.
isOldMultiFrameDICOMIn the case of old multi-frame files we have only one pixel buffer with multiple slices (appears e.g. in RTDose or US images). In these cases we typically also have only one positionDoubles at (0,0,0) which must be applied to the entire image. Will be ignored if positionDoubles contains more than one entry or the first entry is not of position 0,0,0.
Returns
true if dstSubImage was modified during the call, otherwise false.

◆ applyPaletteInfosToPagedImage()

MLDICOM_TO_ML_TOOLS_EXPORT bool ml::DicomToMLTools::applyPaletteInfosToPagedImage ( const DICOMTagTools::DicomPaletteInfo paletteInfos,
PagedImage pagedImage,
const bool  adjustToLUTType = false 
)

If possible then this function modifies pagedImage according to the settings paletteInfos.

Parameters
paletteInfosThe palette information is considered valid if paletteInfos.dataType is MLuint8Type or MLuint16Type.
pagedImageThe PagedImage to be adopted according to the settings in paletteInfos if possible. Input extent in c dimension must be 1. Changed are CDimensionInfos, ImageExtent, and PageExtent.
adjustToLUTTypeIf false, usually the function updates the dataType of PagedImage only if needed but usually remains in the incoming data type; if true, the data type of the palette is used instead to maximize the quality of the color.
Returns
true if pagedImage could be modified successfully according to the settings in paletteInfos, false otherwise. In case of false the pagedImage is left unchanged.

◆ applyPhotometricInterpretationChangesToPagedImage()

MLDICOM_TO_ML_TOOLS_EXPORT bool ml::DicomToMLTools::applyPhotometricInterpretationChangesToPagedImage ( const DCMTree::Const_TreePtr dcmTree,
PagedImage pagedImage 
)

If possible then this function modifies pagedImage according to the photometric interpretation such that pixel values can be translated correctly.

This function should be used together with applyPhotometricInterpretationToSubImg. Currently only MONOCHROME1 and YBR_FULL conversions to RGB are implemented. Do not use this function for PALETTE COLOR conversion; see determinePaletteInformation, applyPaletteInfosToPagedImage, and applySubImageColorLookUp for that purpose.

Parameters
dcmTreeThe palette information is considered valid if paletteInfos.dataType is MLuint8Type or MLuint16Type.
pagedImageThe PagedImage to be adopted according to the DICOM tag "Photometric Interpretation" if possible. Input extent in c dimension must be 1 for MONOCHROME1 and 3 for YBR_FULL. Changes CDimensionInfos, ImageExtent, and PageExtent. For YBR_FULL the voxel data type must be MLuint8Type and a one or two byte type for MONOCHROME1.
Returns
true if pagedImage could be modified successfully, false otherwise. In case of false the pagedImage is left unchanged.

◆ applyPhotometricInterpretationToSubImg()

MLDICOM_TO_ML_TOOLS_EXPORT bool ml::DicomToMLTools::applyPhotometricInterpretationToSubImg ( DCMTree::Const_TreePtr  dcmTree,
const SubImage inSubImg,
const double  minVoxelValue,
const double  maxVoxelValue,
SubImage outSubImg 
)

Applies a color format conversion from input subimage to output subimage according to the photometric interpretation tag in dcmTree.

This function shall be used in conjunction with applyPhotometricInterpretationChangesToPagedImage which should be used to set up the image configuration of the subimages. Currently only MONOCHROME1 and YBR_FULL conversions to RGB are implemented. Do not use this function for PALETTE COLOR conversion; see determinePaletteInformation, applyPaletteInfosToPagedImage, and applySubImageColorLookUp for that purpose.

Parameters
dcmTreeThe DICOM tree from which the information about the color format conversion is retrieved.
inSubImgThe input subimage whose voxels must be of MLuint8Type, MLint8Type, MLuint16Type, or MLint16Type for MONOCHROME1 MLuint8Type for YBR_FULL. Must have same extent in x,y,z,t, and u dimension like outSubImg, and c-extent must be 1 for MONOCHROME1 and 3 for YBR_FULL conversion.
minVoxelValueThe minimum voxel value of the input image; lower voxel values will be clamped against it.
maxVoxelValueThe maximum voxel value of the input image; larger voxel values will be clamped against it.
outSubImgThe output subimage to be filled with the converted color information from inSubImg. Must have same extent in x, y, z, t, and u dimension like inSubImg, and c must be 1 for MONOCHROME1 and 3 for YBR_FULL conversion. Voxel type must be the same as in inSubImg.
Returns
true on success, false otherwise (for example no supported photometric interpretation in dcmTree, invalid image extent or voxel data types).

◆ applySubImageColorLookUp()

MLDICOM_TO_ML_TOOLS_EXPORT bool ml::DicomToMLTools::applySubImageColorLookUp ( const SubImage inSubImg,
const DICOMTagTools::DicomPaletteInfo paletteInfo,

paletteInfoTranslation information from intensity values to color values; it is considered valid if dataType is MLuint8Type or MLint8Type and numEntries are > 0.
outSubImgThe output subimage to be filled with color information looked up from inSubImag via paletteInfo. Must have same extent in x, y, z, t, and u dimension like inSubImg, and c must be 3.
Returns

Traverse all pixel values in the first found pixel data tag in the tree given by treePtr and returns their minimum and maximum values in minValDbl and maxValDbl as well as in minValInt64 and maxValint64.

In case of complex spectroscopy data the data is scanned after decomposing the complex values as twice as many float data. If

  • the tag pointer is nullptr or
  • if it is no pixel data, spectroscopy data or multi-frame data tag or
  • the data type is MLuint64Type or any other non standard data types than complexf then the maximum values are returned with values smaller the minimum values which can easily be tested with (maxVal < minVal) == true.
    Parameters
    treePtrThe DICOM tree whose min/max values shall be determined.
    minValInt64Found minimum value cast to MLint64.
    maxValInt64Found maximum value cast to MLint64.
    minValDblFound minimum value cast to MLdouble.
    maxValDblFound maximum value cast to MLdouble.

size_t  pixelDataSizeInBytes,
ImageVector imgExt,
DicomMessageCollector dcmMsgCollector 
)

Check especially whether the extent of the image given in imgExt is larger by a multiple than the pixel data where the multiple is the same as imgExt.z, imgExt.t or imgExt.z*imgExt.t.

This sometimes happens on frame data exported from multi-frame as single frames where for example NumberOfSlices or NumberOfFrame tags are not correct reset/removed in the written single frame data. This routine can do these correction only if the pixel data tag stores its data in-memory and if it is still inside of the treePtr.

Parameters
treePtrThe DICOM tree from which the image extent was calculated.
imgExtThe extent of the image determined from treePtr and which
pixelDataSizeInBytesThe give number of bytes pixel data used as the true size to compare against the other parameters. shall be checked for inconsistencies and/or corrected.

alternativeDCMTreeIf dcmFileHandle is empty then this tree is used as source to copy from instead. Ignored if dcmFileHandle is not empty.
subImageFilled with the data from subImage or reset to an empty SubImage. The subimage owns the data allocated in the memory manager and will be destroyed automatically with subImage.
dcmMsgCollectorCollects error, info and issue messages (typically related to a handle).
Returns
ML_RESULT_OK if subImage could be set up successfully with image data from the DICOM frame, or another error code describing the problem.

In some cases tags in baseSMFPtr are updated if they do not seem consistent, (e.g. SpacingBetweenSlices) if the DICOM tree structure suggests that. The DICOMTreeImagePropertyextension is also created and appended to the resultImgProps. The frames added to resultImgProps PagedImage resultSMFPtr are copies of the returned srcFrameTrees whose pixel data tags are removed.
    Parameters
    baseSMFPtrThe structured MF tree to be generated/composed and appended to resultImgProps as DICOMTreeImagePropertyExtension.
    firstFileNameThe name of the file to be used as the source file the DICOM image properties come from. If multiple file names are available then that one corresponding to the first DICOM frame should be taken.
    resultImgPropsThe properties to be set up with properties determined from from baseSMFPtr.
    fillPageMethodIf nullptr (the default) it is ignored, otherwise it returns the way how data from the files in the pageFileNames should be copied to ML pages.
    setOfFileHandlesIf it is non nullptr then it is used to create a new structured multi-frame tree in baseSMFPtr. If nullptr is passed (the default) then all following arguments are not used and ignored.

    minMaxCalcModeThe way how min/max value are to be determined from DICOM tags, see CalculateMinMaxFromDicomModes for details.
    versionStringString to be added to the DICOM as private description about the used importer version.
    anonymizeIf true then the created patientIdName and birth date will be anonymized. WARNING: This is only a partial and incomplete anonymization of the DICOM information. For a reliable anonymization other approaches are needed.
    removePrivateMultiFrameSQTagIf true then a private MeVis sequence tag with DICOM frame information will be removed (if it exists) before adding the tree to image properties, otherwise the tag is left unchanged.
    forceOrthogonalWorldMatrixIf enabled then the world matrix is always determined from the first ImageOrientationPatient of the first frame in frame set. use with care because gantry tilted data will be imported with incorrect world matrices then.
    copyPrivateTopLevelSrcTagsIf true then private top level tags from source frames are copied to the baseSMFPtr, otherwise they are removed.
    dcmMsgCollectorCollects error, info and issue messages (typically related to a handle).
    Returns
    A string describing the error or "" on success. resultImgProps will be validated/up to date on successful conversion, otherwise it will be set invalid.

std::vector< DCMTree::RawTagId > *  usedTags,
DicomMessageCollector dcmMsgCollector 
)

Determine the voxel size from the DICOM tags and returns the number of found extents.

All not found extents are filled with 1 if replaceOnlyIfFound==false, otherwise they are only set if they are found.

Parameters
treePtrThe DICOM tree from which the voxel size shall be determined.
isPreciseIf this is passed non nullptr then its return value is set to true if the standard DICOM tags could be retrieved which determine a precise voxel spacing. If tags were used which do not describe the physically exact spacing then false is returned.
  • Tags considered precise are:
    • DCMTree_PixelSpacing
    • DCMTree_SpacingBetweenSlices
    • DCMTree_SliceThickness
    • RTDOSE DCMTree_GridFrameOffsetVector
    • REG DCMTree::TagId(0x0064,0x0008) (=GridResolution)
  • Tags considered imprecise are:
    • DCMTree_PixelAspectRatio,
    • DCMTree_CompensatorPixelSpacing
    • DCMTree_ReconstructionPixelSpacing
    • DCMTree_ImagerPixelSpacing
    • DCMTree_ImagePlanePixelSpacing
    • DCMTree_PresentationPixelSpacing
    • DCMTree_PresentationPixelAspectRatio
    • DCMTree_NominalScannedPixelSpacing
voxSizeXUpdate to the x-extent of voxels if it can be determined from treePtr. If it cannot be determined unchanged if replaceOnlyIfFound, or 1 otherwise.
voxSizeYLike voxSizeX for the y extent of the voxels.
voxSizeZLike voxSizeX for the z extent of the voxels.
replaceOnlyIfFoundIf true then the arguments voxSizeX, voxSizeY, and voxSizeZ are only modified if valid values are found, otherwise they are left unchanged. If case of false these arguments are set to 1 if they cannot be determined.
usedTagsIf this is passed non nullptr then the DICOM tag ids used to determine the voxel size are returned in the vector.
dcmMsgCollectorCollects error, info and issue messages (typically related to a handle).
Returns
The number of found extent dimensions, for example 2 if x and y extent of the voxel size could be determined.

◆ guessMinMaxRangeFromDICOMTags()

MLDICOM_TO_ML_TOOLS_EXPORT bool ml::DicomToMLTools::guessMinMaxRangeFromDICOMTags ( DCMTree::Const_TreePtr  treePtr,
MLdouble minPixVal,
MLdouble maxPixVal,
DicomMessageCollector dcmMsgCollector 
)

Try to guess a min/max range from DICOM tags for the case that they cannot be determined in another way.

The pixel data type, the used bits, the highest bit and stored bit tags can at least limit the min/max range to a useful range if other approaches failed.

Parameters
treePtrThe tree to be checked for min/max pixel tags.
minPixValThe found minimum value if return value is true, otherwise ML_DOUBLE_MAX.
maxPixValThe found maximum value if return value is true, otherwise -ML_DOUBLE_MAX.
dcmMsgCollectorCollects error, info and issue messages (typically related to a handle).
Returns
true if both min/max values were set, false if any of both could not be determined.

◆ hasValidNonImageModality()

MLDICOM_TO_ML_TOOLS_EXPORT bool ml::DicomToMLTools::hasValidNonImageModality ( DCMTree::Const_TreePtr  treePtr)

Returns true only if the passed string is a known, non-empty and valid modality string which is a non image modality (RTSTRUCT, RTPLAN, RTRECORD, AU, SR, HD, ECG, FID...) and the DCMTree is not a Secondary Capture IOD.

The treePtr will also be examined for modalities such as REG whether it is an image like REG deformation field or only Matrix storage and therefore no image. It also will be checked for the Secondary Capture IOD which always is an image modality and which will result to a false return even if the modality tag value indicates a non image one. nullptr treePtrs will be handled as ML error.

◆ isImageFrameNotOfBits()

MLDICOM_TO_ML_TOOLS_EXPORT bool ml::DicomToMLTools::isImageFrameNotOfBits ( DCMTree::Const_TreePtr  treePtr)

Returns true if the DICOM tree seems to describe a sensible image with column and row extents > 1 as well as pixels with more than one bit per pixel, otherwise false.

PixelData presence is not checked, thus it can be used to check frames without pixel data to be image frames.

◆ isVolumeCovered()

MLDICOM_TO_ML_TOOLS_EXPORT bool ml::DicomToMLTools::isVolumeCovered ( const PositionSpecificDoubleVector positions,
const SubImageBox volume 
)

Returns true if the (z,t,u) positions in positions cover all (z,t,u) slices in volume, otherwise false is returned.

◆ rasterOverlays()

MLDICOM_TO_ML_TOOLS_EXPORT std::string ml::DicomToMLTools::rasterOverlays ( DicomToMLTools::FrameSpecificTagsVector overlayTagSet,
SubImage outSubImg 
)

Takes overlay DICOM tags from overlayTagSet matching the x/y plane of outSubImage.getBox().v1, create BitImages from them and copies them into outSubImage where the entire background it filled with 0, and valid overlay bits are set to 1.

The return value is empty on success or if no overlays to render are found, and a descriptive string if anything fails, for example if overlay tags contain inconsistent information.

◆ setUpMinMaxVoxelValues()

MLDICOM_TO_ML_TOOLS_EXPORT void ml::DicomToMLTools::setUpMinMaxVoxelValues ( std::string &  errStr,
DCMTree::Const_DictPtr  dcmTreeDictPtr,
double  smallestPixelValue,
double  largestPixelValue,
DCMTree::TreePtr  dcmTree 
)

Set up DCMTree_SmallestImagePixelValue and DCMTree_LargestImagePixelValue tags in dcmTree; requires that DCMTree_PixelRepresentation, DCMTree_SmallestImagePixelValue, or DCMTree_LargestImagePixelValue tags exist from which the value representation of the DCMTree_SmallestImagePixelValue and DCMTree_LargestImagePixelValue can be determined.

Parameters
errStrOn success errStr is left unchanged, on error the error description is appended.
dcmTreeDictPtrA required dictionary pointer to decode tag names and ids.
smallestPixelValueThe tag value for DCMTree_SmallestImagePixelValue.
largestPixelValueThe tag value for DCMTree_LargestImagePixelValue.
dcmTreeTree to which the tags are added.

◆ setUpOverlayOutputProperties()

MLDICOM_TO_ML_TOOLS_EXPORT void ml::DicomToMLTools::setUpOverlayOutputProperties ( DCMTree::Const_TreePtr  dcmTree,
PagedImage overlayPagedImg,
DicomToMLTools::FrameSpecificTagsVector overlayTagSet 
)

Determine DICOM overlay information from dcmTree, configures (or if necessary invalidates) the passed overlayPagedImg such that it can display these overlays correctly, and sets up overlayTagSet such that it provides all required DICOM tags to display them properly in calculateOutputSubImage.

It is assumed that overlayPagedImg is configured in the same ways as the image on which the overlay lives. As an example: Output image 0 shows a DICOM image and output image 1 shall display its overlays. Then set overlayPagedImg the same properties as output image 0 and then call this function. Specified properties are:

  • ImageExtent to 1 in c.
  • PageExtent to 1 in z, c, t, and u.
  • Voxel type to MLuint8Type.
  • min/max to [0,1].

◆ setWorldMatrixFromDcmTree()

MLDICOM_TO_ML_TOOLS_EXPORT void ml::DicomToMLTools::setWorldMatrixFromDcmTree ( DCMTree::Const_TreePtr  treePtr,
PagedImage outInfos,
DicomMessageCollector dcmMsgCollector 
)

If possible all image properties from the DcmTree needed to set up the world matrix are searched and converted to a world matrix and voxel size and set in outInfos.

If no or only partial values are found then default settings are used instead.

Parameters
treePtrThe DICOM tree the matrix is computed from.
outInfosThe PagedImage in which the worldMatrix is set up as good as possible.
dcmMsgCollectorCollects error, info and issue messages (typically related to a handle).
