Name: Decomposition Method
Keyword: DecompositionMethod
Tag: (0018,937E)
Value Representation: CS
Value Multiplicity: 1

• Described in the contexts:
  • Multi-energy CT Processing Macro > Multi-energy CT Processing Sequence > Decomposition Method
  as follows:
  Attribute Name: Decomposition Method
  Type: 1
  Attribute Description:

  Method used to decompose the acquired Multi-energy CT data into basis data.

  Defined Terms:

  PROJECTION_BASED

  The acquired projection data was fully decomposed into basis projection data (i.e. sinograms).

  IMAGE_BASED

  The acquired projection data was fully reconstructed into images before being decomposed into basis image data.

  HYBRID

  The acquired projection data was reconstructed using knowledge in both projection and image space to produce basis image data. Decomposition and image reconstruction may be performed in a one-step approach.

  Note

  1. Basis images and basis projection data are not necessarily instantiated as DICOM Instances.

  2. There may be additional processing steps (e.g. linear combination of basis data) creating the result image.
