C.36.2.4.6.1 KV Radiation Image Acquisition Parameters Macro Attribute Descriptions

C.36.2.4.6.1.1 Imaging Energy Category Code Sequence

The Imaging Energy can be described in either Energy Derivation Code Sequence (3002,0133) or KVP (0018,0060).

When KVP (0018,0060) is present and has no value, no Imaging Energy is described.
