Attribute Description

Monoenergetic Energy Equivalent

(0018,937C)

1C

Single energy equivalent in keV.

Required if Image Type (0008,0008) Value 4 is EQUAL to VMI. May be present otherwise.

Note

If the Image Type Value 4 is (MAT_REMOVED, MAT_MODIFIED) and a VMI image was used as the source then this value reflects the keV value of the VMI image.

Derivation Algorithm Sequence

(0022,1612)

3

Software algorithm that performed the derivation.

>Include Table 10-19 “Algorithm Identification Macro Attributes”

Performed Processing Parameters Sequence

(0074,1212)

3

Parameters used to perform the derivation algorithm.

Note

Implementers are encouraged to put the Algorithm Parameters here instead of in Algorithm Parameters (0066,0032) in the Algorithm Identification Macro

One or more items are permitted in this Sequence.
