Optical Path Sequence Attribute

Tag(0048,0105)
TypeRequired (1)
KeywordOpticalPathSequence
Value Multiplicity1
Value RepresentationSequence (SQ)

Describes the optical paths used during the acquisition of this image.

One or more Items shall be included in this Sequence.

See Section C.8.12.5.1.1

Section C.8.12.5.1.1

C.8.12.5.1.1 Optical Path Sequence and Optical Path Identifier

The Optical Path Sequence (0048,0105) shall include an Item for every optical path used in the acquisition of the current image.

For single-frame images that do not include the Multi-frame Functional Groups Module, this Sequence shall include only one Item.

For images that use the Multi-frame Functional Groups Module, the optical path associated with each frame is identified by reference to the Optical Path Identifier (0048,0106) of this Sequence (see Optical Path Identification Sequence (0048,0207) in Section C.8.12.6.2). The Optical Path Sequence may include Items for defined optical paths that are not referenced by any frame.

Note

  1. Previously, the use of optical paths in LOCALIZER images and images referenced therein from the Section C.8.12.7 was described, but this usage has been retired. See PS3.3-2021c.

  2. The Optical Path Identifier is not necessarily numeric; it is a string of up to 16 characters (VR SH).
