  1. (0018,1111) Vs (0018,x402)


    I am confused about definitions of (0018, 1111):

    NEMA/DICOM has two different definitions for (0018, 1111) tag.
    "Distance from Source to Patient" in XA IOD
    and
    "Distance in mm from source to isocenter" in CR IOD.

    Vendor definitions also vary.

    As per link below, tag (0018, x402) has a definiton
    of "Distance from source to isocenter in mm":
    http://medical.nema.org/Dicom/minute...n/sup83_13.doc

    If some one wants to know "Distance from source to isocenter in mm"
    which tag should I look for?

    Thanks in advance..

    In Base standard 2004, P3 XA IOD has (0018,1111) as

    "Distance from source to isocenter in mm".

    I will stick with this.
