Summary0008476: itkPhilipsRECImageIO throws an exception when reading 4D images.
DescriptionIn PhilipsRECImageIO, the direction cosines are not defined for dimensions higher than 3. Therefore, a 4D image with default orientation would have it direction set to {{1, 0, 0, 0}, {0, 1, 0, 0}, {0, 0, 1, 0}, {0, 0, 0, 0}}.

Note that the last direction vector is all zeros. This causes an exception when the direction is validated, as {0, 0, 0, 0} does not define a valid orientation in space (See ComputeIndexToPhysicalPointMatrices() in itkImageBase.txx).

A solution would be to initialize the direction of the last direction to {0, 0, 0, 1}.

A proposed patch is attached.

Confirmed the bug. When trying to read a 4D Philips REC image using ITK 3.10.2, an exception is thrown when the direction cosines are checked.
