Image position not correctly read from Siemens mosaic DICOM files

Detailed description

This is parsed from Siemens CSA header, but apparently not correctly. To verify, use image location to align mosaic with non-mosaic series from the same study - should match but doesn't.

Apparently the CSA header information related to the location of the CENTER voxel, not CORNER voxel, in a given slice.

Also, it seems the standard-DICOM ImagePosition tag specifies the origin of an image the size of the entire mosaic, if such had been acquired.
