The date and time that the acquisition of data that resulted in this image started. Note: The synchronization of this time with an external clock is specified in the Synchronization Module in Acquisition Time Synchronized (0018,1800).
(0008,1140) Referenced Image Sequence
3
A sequence that references other images significantly related to this image (e.g. post-localizer CT image or Mammographic biopsy or partial view images).
(0008,1150) >Referenced SOP Class UID
1C
Uniquely identifies the referenced SOP Class. Required if Referenced Image Sequence (0008,1140) is sent.
(0008,1155) >Referenced SOP Instance UID
1C
Uniquely identifies the referenced SOP Instance. Required if Referenced Image Sequence (0008,1140) is sent.
(0008,1160) >Referenced Frame Number
3
References one or more image frames of a Multi-frame Image SOP Instance, identifying which frames are significantly related to this image, and the reference is not to all frames. Note: If this Attribute is not present, all frames of the SOP Instance are referenced.
(0040,A170) >Purpose of Reference Code Sequence
3
Describes the purpose for which the reference is made.
(0008,2111) Derivation Description
3
A text description of how this image was derived. See C.7.6.1.1.3 for further explanation.
(0008,9215) Derivation Code Sequence
3
A coded description of how this image was derived. See C.7.6.1.1.3 for further explanation.
(0008,2112) Source Image Sequence
3
A Sequence that identifies the set of Image SOP Class/Instance pairs of the Images that were used to derive this Image. Zero or more Items may be included in this Sequence. See C.7.6.1.1.4 for further explanation.
(0008,1150) >Referenced SOP Class UID
1C
Uniquely identifies the referenced SOP Class. Required if Source Image Sequence (0008,2112) is sent.
(0008,1155) >Referenced SOP Instance UID
1C
Uniquely identifies the referenced SOP Instance. Required if Source Image Sequence (0008,2112) is sent.
(0008,1160) >Referenced Frame Number
3
References one or more image frames of a Multi-frame Image SOP Instance, identifying which frames were used to derive this image, and the reference is not to all frames. Note: If this Attribute is not present, all frames of the SOP Instance are referenced.
(0040,A170) >Purpose of Reference Code Sequence
3
Describes the purpose for which the reference is made, that is what role the source image or frame(s) played in the derivation of this image.
(0008,113A) Referenced Waveform Sequence
3
References to waveforms acquired in conjunction with this image. These Waveforms may or may not be temporally synchronized with this image. One or more Items may be included in this Sequence.
(0040,A170) >Purpose of Reference Code Sequence
1
Code describing the purpose of the reference to the waveform(s). Only a single Item shall be permitted in this sequence.
(0020,1002) Images in Acquisition
3
Number of images that resulted from this acquisition of data
(0020,4000) Image Comments
3
User-defined comments about the image
(0028,0300) Quality Control Image
3
Indicates whether or not this image is a quality control or phantom image. Enumerated Values: YES NO If this Attribute is absent, then the image may or may not be a quality control or phantom image.
(0028,0301) Burned In Annotation
3
Indicates whether or not image contains sufficient burned in annotation to identify the patient and date the image was acquired . Enumerated Values: YES NO If this Attribute is absent, then the image may or may not contain burned in annotation.
(0028,2110) Lossy Image Compression
3
Specifies whether an Image has undergone lossy compression. Enumerated Values: 00 = Image has NOT been subjected to lossy compression. 01 = Image has been subjected to lossy compression. See C.7.6.1.1.5
(0028,2112) Lossy Image Compression Ratio
3
Describes the approximate lossy compression ratio(s) that have been applied to this image. See C.7.6.1.1.5 for further explanation. May be multivalued if successive lossy compression steps have been applied. Notes: 1. For example, a compression ratio of 30:1 would be described in this Attribute with a single value of 30. 2. For historical reasons, the lossy compression ratio should also be described in Derivation Description (0008,2111).
(0088,0200) Icon Image Sequence
3
This icon image is representative of the Image.
(2050,0020) Presentation LUT Shape
3
When present, specifies an identity transformation for the Presentation LUT such that the output of all grayscale transformations, if any, are defined to be in P-Values. Enumerated Values are: IDENTITY - output is in P-Values - shall be used if Photometric Interpretation (0028,0004) is MONOCHROME2 or any color photometric interpretation. INVERSE - output after inversion is in P-Values - shall be used if Photometric Interpretation (0028,0004) is MONOCHROME1. When this attribute is used with a color photometric interpretation then the luminance component is in P-Values.
