DICOMReader incorrectly reads world coordinates from DICOM #199

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago

For a pair of test MRIs I have verified that the DICOMReader incorrectly reads 
the world coordinates, whereas similar readers (MITK) reads the same data 
correctly.

This error makes it impossible to automatically superimpose pre-aligned DICOM 
sets taken with different extents or orientations.

The world coordinates are correct for most images, but (for example) incorrect 
for a coronally scanned MRI dataset in my possession.

DICOMReader.py line 44 might be related to this problem:
self._reader.SetFileLowerLeft(1)
Although flipping this switch to zero doesn't resolve the issue (it does change 
the output world coordinates though)
