BTW, here is what I got by running gdcminfo (gdcm version 2.4.0) on one of the dicoms: ====================================================================== MediaStorage is 1.2.840.10008.5.1.4.1.1.7 [Secondary Capture Image Storage] TransferSyntax is 1.2.840.10008.1.2.1 [Explicit VR Little Endian] NumberOfDimensions: 2 Dimensions: (512,512,1) SamplesPerPixel :1 BitsAllocated :16 BitsStored :16 HighBit :15 PixelRepresentation:1 ScalarType found :INT16 PhotometricInterpretation: MONOCHROME2 PlanarConfiguration: 0 TransferSyntax: 1.2.840.10008.1.2.1 Origin: (0,0,0) Spacing: (1,1,1) DirectionCosines: (1,0,0,0,1,0) Rescale Intercept/Slope: (-1024,1) Orientation Label: AXIAL =======================================================================
Clearly, from (0018,0088)=0.449999988 (0028,0030)=0.400391012\0.400391012 The spacing should not be (1,1,1).
