vtkDICOMImageReader Class Reference
#include <vtkDICOMImageReader.h>
Detailed Description
Reads some DICOM images.DICOM (stands for Digital Imaging in COmmunications and Medicine) is a medical image file format widely used to exchange data, provided by various modalities.
- Warning:
- This reader might eventually handle ACR-NEMA file (predecessor of the DICOM format for medical images). This reader does not handle encapsulated format, only plain raw file are handled. This reader also does not handle multi-frames DICOM datasets.
Internally DICOMParser assumes the x,y pixel spacing is stored in 0028,0030 and that z spacing is stored in Slice Thickness (correct only when slice were acquired contiguous): 0018,0050. Which means this is only valid for some rare MR Image Storage

| void vtkDICOMImageReader::PrintSelf | ( | ostream & | os, | |
| vtkIndent | indent | |||
| ) | [virtual] |
Prints the ivars.
Reimplemented from vtkImageReader2.
| void vtkDICOMImageReader::SetFileName | ( | const char * | fn | ) | [inline, virtual] |
Set the filename for the file to read. If this method is used, the reader will only read a single file.
Reimplemented from vtkImageReader2.
Definition at line 68 of file vtkDICOMImageReader.h.
| void vtkDICOMImageReader::SetDirectoryName | ( | const char * | dn | ) |
Set the directory name for the reader to look in for DICOM files. If this method is used, the reader will try to find all the DICOM files in a directory. It will select the subset corresponding to the first series UID it stumbles across and it will try to build an ordered volume from them based on the slice number. The volume building will be upgraded to something more sophisticated in the future.
| virtual char* vtkDICOMImageReader::GetDirectoryName | ( | ) | [virtual] |
Returns the directory name.
| double* vtkDICOMImageReader::GetPixelSpacing | ( | ) |
Returns the pixel spacing (in X, Y, Z). Note: if there is only one slice, the Z spacing is set to the slice thickness. If there is more than one slice, it is set to the distance between the first two slices.
| int vtkDICOMImageReader::GetWidth | ( | ) |
Returns the image width.
| int vtkDICOMImageReader::GetHeight | ( | ) |
Returns the image height.
| float* vtkDICOMImageReader::GetImagePositionPatient | ( | ) |
Get the (DICOM) x,y,z coordinates of the first pixel in the image (upper left hand corner) of the last image processed by the DICOMParser
| float* vtkDICOMImageReader::GetImageOrientationPatient | ( | ) |
Get the (DICOM) directions cosines. It consist of the components of the first two vectors. The third vector needs to be computed to form an orthonormal basis.
| int vtkDICOMImageReader::GetBitsAllocated | ( | ) |
Get the number of bits allocated for each pixel in the file.
| int vtkDICOMImageReader::GetPixelRepresentation | ( | ) |
Get the pixel representation of the last image processed by the DICOMParser. A zero is a unsigned quantity. A one indicates a signed quantity
| int vtkDICOMImageReader::GetNumberOfComponents | ( | ) |
Get the number of components of the image data for the last image processed.
| const char* vtkDICOMImageReader::GetTransferSyntaxUID | ( | ) |
Get the transfer syntax UID for the last image processed.
| float vtkDICOMImageReader::GetRescaleSlope | ( | ) |
Get the rescale slope for the pixel data.
| float vtkDICOMImageReader::GetRescaleOffset | ( | ) |
Get the rescale offset for the pixel data.
| const char* vtkDICOMImageReader::GetPatientName | ( | ) |
Get the patient name for the last image processed.
| const char* vtkDICOMImageReader::GetStudyUID | ( | ) |
Get the study uid for the last image processed.
| const char* vtkDICOMImageReader::GetStudyID | ( | ) |
Get the Study ID for the last image processed.
| float vtkDICOMImageReader::GetGantryAngle | ( | ) |
Get the gantry angle for the last image processed.
| virtual int vtkDICOMImageReader::CanReadFile | ( | const char * | fname | ) | [virtual] |
| virtual const char* vtkDICOMImageReader::GetFileExtensions | ( | ) | [inline, virtual] |
Get the file extensions for this format. Returns a string with a space separated list of extensions in the format .extension
