GENERAL IMAGE MODULE ATTRIBUTES (C.7-9)


Tag Attribute Type Description
(0020,0013)Instance Number2 A number that identifies this image. Note: This Attribute was named Image Number in earlier versions of this Standard.
(0020,0020)Patient Orientation2C Patient direction of the rows and columns of the image. Required if image does not require Image Orientation (Patient) (0020,0037) and Image Position (Patient) (0020,0032). See C.7.6.1.1.1 for further explanation.
(0008,0023)Content Date2C The date the image pixel data creation started. Required if image is part of a series in which the images are temporally related. Note: This Attribute was formerly known as Image Date.
(0008,0033)Content Time2C The time the image pixel data creation started. Required if image is part of a series in which the images are temporally related.
(0008,0008)Image Type3 Image identification characteristics. See C.7.6.1.1.2 for Defined Terms and further explanation.
(0020,0012)Acquisition Number3 A number identifying the single continuous gathering of data over a period of time that resulted in this image.
(0008,0022)Acquisition Date3 The date the acquisition of data that resulted in this image started
(0008,0032)Acquisition Time3 The time the acquisition of data that resulted in this image started
(0008,002A)Acquisition Datetime3 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 Sequence3 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 UID1C Uniquely identifies the referenced SOP Class. Required if Referenced Image Sequence (0008,1140) is sent.
(0008,1155)>Referenced SOP Instance UID1C Uniquely identifies the referenced SOP Instance. Required if Referenced Image Sequence (0008,1140) is sent.
(0008,1160)>Referenced Frame Number3 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 Sequence3 Describes the purpose for which the reference is made.
(0008,2111)Derivation Description3 A text description of how this image was derived. See C.7.6.1.1.3 for further explanation.
(0008,9215)Derivation Code Sequence3 A coded description of how this image was derived. See C.7.6.1.1.3 for further explanation.
(0008,2112)Source Image Sequence3 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 UID1C Uniquely identifies the referenced SOP Class. Required if Source Image Sequence (0008,2112) is sent.
(0008,1155)>Referenced SOP Instance UID1C Uniquely identifies the referenced SOP Instance. Required if Source Image Sequence (0008,2112) is sent.
(0008,1160)>Referenced Frame Number3 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 Sequence3 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 Sequence3 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 Sequence1 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 Acquisition3 Number of images that resulted from this acquisition of data
(0020,4000)Image Comments3 User-defined comments about the image
(0028,0300)Quality Control Image3 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 Annotation3 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 Compression3 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 Ratio3 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 Sequence3 This icon image is representative of the Image.
(2050,0020)Presentation LUT Shape3 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.
