|---|---|
| Type | Optional (3) |
| Keyword | InConcatenationTotalNumber |
| Value Multiplicity | 1 |
| Value Representation | Unsigned Short (US) |
The number of SOP Instances sharing the same Concatenation UID.

|
Lossy Image Compression Ratio |
(0028,2112) |
1C |
Describes the approximate lossy compression ratio(s) that have been applied to this image. Required if Lossy Image Compression (0028,2110) is "01". |
|
Lossy Image Compression Method |
(0028,2114) |
1C |
A label for the lossy compression method(s) that have been applied to this image. Required if Lossy Image Compression (0028,2110) is "01". |

|
|
Recognizable Visual Features |
(0028,0302) |
3 |
Indicates whether or not the image contains sufficiently recognizable visual features to allow the image or a reconstruction from a set of images to identify the patient. Enumerated Values:
If this Attribute is absent, then the image may or may not contain recognizable visual features. |
|
Concatenation Frame Offset Number |
(0020,9228) |
1 |
Offset of the first frame in a multi-frame image of a concatenation. Enumerated Values:
|
|
In-concatenation Number |

1 |
Identifier for one SOP Instance belonging to a concatenation. Enumerated Values:
|
|
In-concatenation Total Number |
(0020,9163) |
1 |
The number of SOP Instances sharing the same Concatenation UID (0020,9161). See Section C.8.17.16.3 for further explanation. Enumerated Values:
|
|
Image Comments |
(0020,4000) |
3 |
User-defined comments about the image. |
The value constraints on Concatenation Frame Offset Number (0020,9228), In-concatenation Number (0020,9162), and In-concatenation Total Number (0020,9163) have the effect of preventing the use of concatenations.
The Attribute Ophthalmic Volumetric Properties Flag (0022,1622) is YES when the Ophthalmic Tomography Image Storage SOP Instance encodes volumetric spatial information (e.g. Frame of Reference, Pixel Measures, Plane Orientation, Plane Position, etc.). For example, ophthalmic tomography volumetric information is required when implementations encode Surface Segmentation SOP Instance(s) (e.g., surface segmentation is applied to the structural OCT volume to delineate the anatomical boundaries) and/or an Ophthalmic Optical Coherence Tomography B-scan Volume Analysis Storage SOP Instance (e.g., angiographic (blood flow) volume information) based upon the volumetric Ophthalmic Tomography Image Storage SOP Instance.
