##### C.8.2.2.3 Multi-energy CT Path Macro

A Multi-energy CT Path is an X-Ray source paired with a corresponding X-Ray detector for a particular energy level.

Table C.8.2.2-4. Multi-energy CT Path Macro Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Multi-energy CT Path Sequence | (0018,9379) | 1 | Describes the paths corresponding to each energy level of a Multi-energy acquisition. Each path consists of a source (see Section C.8.2.1.1.1) and a detector (see Section C.8.2.2.1.1). Two or more Items shall be included in this Sequence. See also Section C.8.2.2.1 and Section C.8.2.2.2.
>Multi-energy CT Path Index | (0018,937A) | 1 | Identification number of the element in the Multi-energy CT Path Sequence. The number shall be 1 for the first Item and increase by 1 for each subsequent Item.
>Referenced X-Ray Source Index | (0018,9377) | 1 | References the X-Ray Source Index (0018,9366) in the Multi-energy CT X-Ray Source Sequence (0018,9365) in this path.
>Referenced X-Ray Detector Index | (0018,9376) | 1 | References the X-Ray Detector Index (0018,9370) in the Multi-energy CT X-Ray Detector Sequence (0018,936F) in this path.
