hi everyone I got a code for DICOM viewer in this link: http://www.mathworks.com/matlabcentral/fileexchange/4172-dicom-viewer
The thickness of each slice is important for me. in this code I can see this but I don't know Is this measured at the millimeter level? my question is this: how can I get that the thickness of one slice of a CT image is measured at the millimeter level? if it is not measured in millimeter how can I transfer it to millimeter? I appreciate your helps and supports in advanced.

Yes, DICOM tag (0018,0050) Slice Thickness is in mm. See http://medical.nema.org/Dicom/2011/11_03pu.pdf Table C.7-10
Note that Slice Thickness is allowed to be different for different slices. There is a useful discussion at https://groups.google.com/forum/#!topic/comp.protocols.dicom/_VwpyrH36xw

thanks dear Walter Roberson
these links are very helpful for me. excuse me, but I can't see DICOM tag (0018,0050) in this code. ( http://www.mathworks.com/matlabcentral/fileexchange/4172-dicom-viewer )

Read tags only, not the image:
info = dicominfo('filename.dcm');
Get slice thickness in mm:
info.SliceThickness

Right, SliceThickness is the tag name associated with (0018,0050)
