Scope and Field of Application
Supplement 188 (reproduced from the document for convenience:)

This Supplement extends the CT Image IOD and Enhanced CT Image IOD to support new types of images generated by Multi-energy (ME) CT scanners. It describes various ME imaging techniques. While different vendors apply different techniques to achieve Multi-energy images, there is large commonality in the generated diagnostic images. It adapts existing attributes of the CT / Enhanced CT IOD to fit ME techniques.

Who can vote? Only the designated Primary voting representatives of the DSC member organizations/companies are invited and entitled to vote. (Votes may also be submitted by the designated Alternate voting representatives, on behalf of the Primary representative.) (Others in the DICOM Community will receive a copy of this ballot as a courtesy so that all will be apprised of anticipated extensions to the DICOM Standard.)
