19 /* Raisons ne pas utiliser itkImageSeriesReader:
21 On Wed, Feb 16, 2011 at 11:51 AM, Roger Bramon Feixas <rogerbramon@gmail.com>
23 I'm developing with ITK 3.20 + GDCM 2.0.17 + VTK 5.6 and I've noticed
24 itkImageSeriesReader is ~2x slower than vtkGDCMImageReader (from GDCM2).
25 I compared both codes and I think the difference is the extra copy which
26 itkImageSeriesReader makes from ImageFileReader's output to its own output
27 (ImageSeriesReader::GenerateData() line 393).
31 /* ====================================================================
34 3D, 2D+T, 3D+T, n*2D+T, 4D images are not always stored the same way :
35 a single 'Dicom Serie',
36 several 'Dicom series' within a single directory
37 several 'Dicom series' within several directories
38 A 'Dicom Serie' doesn't mean always the same thing :
39 a given Slice along the time
40 a given Volume at a given time
41 Sometimes, an image within a serie is so artefacted than user decides to replace
44 User needs to be aware, *only him* knows want he wants to do.
45 vtkGdcm4DSplitter class does the job for hom
46 (despite its name, it works on 3D or 2D+T images too)
48 User will have to specify some points
54 bool setDirName(std::string &dirName);
55 - a list of directories
56 bool setVectDirName(std::vector<std::string> &vectDirName);
58 bool setVectFileName(std::vector<std::string> &vectFileName);
60 - Recursive directory exploration
61 void setRecursive(bool recursive);
63 . Choose 'split' criterion :
64 ---------------------------
66 - ImagePositionPatient
67 void setSplitOnPosition();
68 - ImageOrientationPatient
69 void setSplitOnOrientation();
71 void setSplitOnTag(unsigned short splitGroup, unsigned short splitElem);
72 void setSplitConvertToFloat(bool conv);
73 - UserDefined Function
74 void setSortOnUserFunction (FoncComp f);
76 for 'true' 3D image sets :
77 - if you want to get a single 3D vtkImageData, use SplitOnOrientation -i.e. no split-
78 - if you want to get a vector of 2D vtkImageData, use SplitOnPosition -i.e. one slice in each 'XCoherent filesite'-
80 for 'true' 4D multi-orientation image sets (i.e. a stack of axial + sagital + coronal images, at different instants ...)
81 --> this is 5D, right?
85 . Choose 'sort' criterion :
86 --------------------------
88 - ImagePositionPatient
89 void setSortOnPosition();
90 - ImageOrientationPatient
91 ==> Only in your dreams!
92 ==> or, please, write a IOP sorter ...
93 - UserDefined Function
94 void setSortOnUserFunction (FoncComp f);
96 void setSortOnFileName()
105 -a single vtkImageData:
106 vtkImageData *GetImageData();
107 - a vector of vtkImageData
108 std::vector<vtkImageData*> *GetImageDataVector();
