Detailed Description

Oblique extention to vtkImageData. This class contains a length 9 double array to contain the directional cosine matrix. Using this methods like "GetPoint" and "GetCell" can be overridden to cause the oblique nature of the dataset to be accurately represented. NOTE: Many of the methods are not implemented currently, only those that are necessary for the filters/actors that we are using to represent image data.

Note, the svkImageData's DICOM header (svkDcmHeader) contains the following fields that define the data orientation:

imageOrientationPatient (the row and column vector that define the slice plane).
imagePositionPatient (the explicit position of each slice (frame))

The "right handed" normal to the plane defined by 1, gives the positive S direction (for an Axial Data Set).

The data ordering or 3rd row of the DCOS matrix is implicitly given by the coordinates in consecutive imagePositionPatient fields for each frame.

Data ordering is only explicitly encoded in the 3x3 DCOS in the svkImageData object to indicate the spatial relation of data buffer ordering.

protected

This projects a posLPS onto a normal vector through the real world origin. This is a common reference vector for both the MRI and MRS data. The projection is normalized by the relevant data slice spacing to get the nearest slice.

This method takes the origin and spacing as input so that it can be used for single voxel data as well as normal image and spectra.

If the matching slice is beyond the defined tolerance than -1 is returned.

Parameters

posLPS	the lps coordinate to match against
sliceOrientation	the orientation to match against
origin	the origin to use for the matching.
spacing	the spacing to use for the matching
tolerance	the maximum permissible distance for a match

Returns: the closest slice. If the slice is outside the tolerance then -1 is returned
