[Insight-users] scale of a pixel

[Luis Ibanez]

Hi Raquel,


In oder to find the pixel spacing of a DICOM image
you can use:


Method (A): Load the image and call: reader->GetOutput()->Print(std::cout);

Method (B): Load the image and call:
         std::cout << reader->GetOutput()->GetSpacing() << std::endl;

Method (C): Use the example:
        Insight/Examples/IO/DicomImageReadPrintTags.cxx
        and grep for
        (0028|0030) Pixel Spacing

        you should see something like:
        (0028|0030) Pixel Spacing = 0.93359375\0.93359375
        (which are the spacing in X and Y)


Method (D): Use VV (http://www.creatis.insa-lyon.fr/rio/vv)
        load the image and look at the image information

Method (E): Use Slicer (www.slicer.org) load the image and
        look at the image information

Method (F): Use MRIConvert :
       http://lcni.uoregon.edu/~jolinda/MRIConvert/
       load one slice and look at the DICOM tags, just as with
       method (C).


   Regards,


         Luis
