* @class vtkMetaImageWriter
|
|
* @brief write a binary UNC meta image data
|
|
*
|
|
* One of the formats for which a reader is already available in the toolkit is
|
|
* the MetaImage file format. This is a fairly simple yet powerful format
|
|
* consisting of a text header and a binary data section. The following
|
|
* instructions describe how you can write a MetaImage header for the data that
|
|
* you download from the BrainWeb page.
|
|
*
|
|
* The minimal structure of the MetaImage header is the following:
|
|
*
|
|
* NDims = 3
|
|
* DimSize = 181 217 181
|
|
* ElementType = MET_UCHAR
|
|
* ElementSpacing = 1.0 1.0 1.0
|
|
* ElementByteOrderMSB = False
|
|
* ElementDataFile = brainweb1.raw
|
|
*
|
|
* * NDims indicate that this is a 3D image. ITK can handle images of
|
|
* arbitrary dimension.
|
|
* * DimSize indicates the size of the volume in pixels along each
|
|
* direction.
|
|
* * ElementType indicate the primitive type used for pixels. In this case
|
|
* is "unsigned char", implying that the data is digitized in 8 bits /
|
|
* pixel.
|
|
* * ElementSpacing indicates the physical separation between the center of
|
|
* one pixel and the center of the next pixel along each direction in space.
|
|
* The units used are millimeters.
|
|
* * ElementByteOrderMSB indicates is the data is encoded in little or big
|
|
* endian order. You might want to play with this value when moving data
|
|
* between different computer platforms.
|
|
* * ElementDataFile is the name of the file containing the raw binary data
|
|
* of the image. This file must be in the same directory as the header.
|
|
*
|
|
* MetaImage headers are expected to have extension: ".mha" or ".mhd"
|
|
*
|
|
* Once you write this header text file, it should be possible to read the
|
|
* image into your ITK based application using the itk::FileIOToImageFilter
|
|
* class.
