Mark,

	This is defined in the supplements (page 14):

http://medical.nema.org/Dicom/supps/sup48_08.pdf

Pixel Spacing (0028,0030) 2 Physical distance in the patient between the
center of each pixel, specified by a numeric pair - adjacent row spacing
(delimiter) adjacent column spacing, in mm. Note the two values shall be
the same for 1\1 aspect ratio. See C.8.X.1.8
