DESCRIPTION

66       Convert a file supported by VTK into DICOM.
67
68       Typical usage is:
69
70           $ gdcm2vtk inputfile output.dcm
71
72       It uses the internal factory mechanism of VTK to recognize a file
73       (CanRead function). See VTK supported file here:
74
75             What image file formats can VTK read and write? http://www.vtk.org/Wiki/VTK_FAQ#What_image_file_formats_can_VTK_read_and_write.3F
76
77       If your input file has 4 components, the 4th comp (alpha) will be
78       removed from the output file as DICOM does not support alpha component
79       anymore (see –argb option).
80
81       Special care was taken for the following file format:
82
83              1. DICOM: Direction Cosines and vtkMedicalImageInformation are passed to the output
84              2. BMP: The file can be saved with a Lookup Table (see --palette-color)
85              3. GE Signa: vtkMedicalImageProperties is passed to the output
86              4. MINC: Direction Cosines is passed to the output
87              5. TIFF: vtkTIFFReader is currently in bad shape in VTK (different behavior in VTK 5.2 and git/master). Only use it, if you know what you are doing.
88
89   CONVERT MetaImage (mhd, mha)
90           $ gdcm2vtk inputfile output.mha
91
92       This command will convert the input DICOM file: inputfile into a
93       MetaImage .mha file. Same goes for .mhd file.
94
95   CONVERT MHA/MHD
96           $ gdcm2vtk inputfile output.mha
97
98       or
99
100           $ gdcm2vtk inputfile output.mhd
101
102       This command will convert the input DICOM file: inputfile into a
103       MetaImageData .mha/.mhd file.
104
105   CONVERT VTI
106           $ gdcm2vtk inputfile output.vti
107
108       This command will convert the input DICOM file: inputfile into a XML
109       VTK ImageData .vti file.
110
111   CONVERT VTK
112           $ gdcm2vtk inputfile output.vtk
113
114       This command will convert the input DICOM file: inputfile into an old
115       VTK Structured PointSets .vtk file.
116

CONVERT DICOM

118           $ gdcm2vtk input.dcm output.dcm
119
120       vtkGDCMImageReader will be used to read in a DICOM file, not the
121       default vtkDICOMImageReader. See option –use-vtkdicom to use
122       vtkDICOMImageReader.
123

ROUNDTRIP DICOM TO MHD TO DICOM

125           $ gdcm2vtk input_ybr.dcm output.mhd
126           $ gdcm2vtk --modality US --imageformat 7 output.mhd output.dcm
127
128       The above refsection shows how to convert a DICOM using the Photometric
129       Interpretation of YBR_FULL (or even YBR_FULL_422 is lossy) into another
130       file format: MetaImage (mhd). Since this file format does not handle
131       color space, we have to explicitly set it using the –imageformat
132       command line option. The –modality command line option is required in
133       this case since the default Secondary Capture Image Storage Class
134       family does not allow for YBR Photometric Interpretation.
135

GDCM2VTK NOTES

137       IMPORTANT NOTE: The internal VTK structured will be filled from the
138       input DICOM, and then pass to the output DICOM writer. Some information
139       might be lost during the conversion DICOM to VTK to DICOM. This option
140       is mostly used to test the vtkGDCMImageReader/vtkGDCMImageWriter
141       combination.
142
143       IMPORTANT NOTE: When converting from a lossy format such as JPEG, the
144       information of lossiness is important. The output DICOM will contains
145       the required Lossy Image Compression attribute that indicates that
146       image was lossy-compressed somewhere along the pipeline. See also
147       gdcmimg (better handling of JPEG in general).
148
149       IMPORTANT NOTE: When using –use-vtkdicom the output DICOM file will
150       always be written as MR Image Storage as this information is not
151       available from the reader itself. This allow setting the Image
152       Orientation (Patient) properly.
