    public class VirtualSourceAxisDistances
    extends org.dcm4che.typeddicom.AbstractDataElementWrapper
    implements FloatingPointSingleMultiWrapper
    Name: Virtual Source-Axis Distances
    Keyword: VirtualSourceAxisDistances
    Tag: (300A,030A)
    Value Representation: FloatingPointSingle
    Value Multiplicity: 2
    • Described in the contexts: as follows:
      Attribute Name: Virtual Source-Axis Distances
      Type: 1
      Attribute Description:

      Distance (in mm) from virtual source position to gantry rotation axis or nominal isocenter position (fixed beam-lines) of the equipment to be used for beam delivery. Specified by a numeric pair - the VSAD in the IEC Gantry X direction followed by the VSAD in the IEC Gantry Y direction.

      The VSAD is commonly used for designing apertures in contrast to the effective source-axis-distance (ESAD) that is commonly used with the inverse square law for calculating the dose decrease with distance. See DICOM Standard Part 3 - Section C.8.8.25.4.
