Table C.8.22-3 specifies the Attributes of the Enhanced PET Image Module.
Table C.8.22-3. Enhanced PET Image Module Attributes
Image characteristics. See Section C.8.22.3.1.1. |
|||
Include Table C.8-131 “Common CT/MR and Photoacoustic Image Description Macro Attributes” |
|||
A number identifying the single continuous gathering of data over a period of time that resulted in this image, which may include multiple bed positions. |
|||
The date and time that the acquisition of data started. Note
Required if Image Type (0008,0008) Value 1 of this frame is ORIGINAL and SOP Class UID is not "1.2.840.10008.5.1.4.1.1.128.1" (Legacy Converted), may be present otherwise. |
|||
The time in seconds needed to complete the acquisition of data. See Section C.7.6.16.2.2.1 for further explanation. Required if Image Type (0008,0008) Value 1 of this frame is ORIGINAL and SOP Class UID is not "1.2.840.10008.5.1.4.1.1.128.1" (Legacy Converted), may be present otherwise. |
|||
Include Table 10.42-1 “Hierarchical Evidence Reference Macro Attributes” |
|||
Number of samples (planes) in this image. This value shall be 1. |
|||
Specifies the intended interpretation of the pixel data. See Section C.7.6.3.1.2 for definition of this term. |
|||
Number of bits allocated for each pixel sample. Each sample shall have the same number of bits allocated. This value shall be 16. |
|||
Number of bits stored for each pixel sample. Each sample shall have the same number of bits stored. This value shall be 16. |
|||
Most significant bit for pixel sample data. Each sample shall have the same high bit. Shall be one less than the value in Bits Stored (0028,0101). |
|||
Content Qualification Indicator See Section C.8.13.2.1.1 for further explanation. |
|||
Indicates that the image does not contain burned in annotations. This means that images that contain this Module shall not contain burned in annotations. Required if SOP Class UID is not "1.2.840.10008.5.1.4.1.1.128.1" (Legacy Converted), may be present otherwise. |
|||
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. If this Attribute is absent, then the image may or may not contain recognizable visual features. |
|||
Specifies whether an Image has undergone lossy compression (at a point in its lifetime). Enumerated Values: Once this value has been set to "01" it shall not be reset. See Section C.7.6.1.1.5. Required if SOP Class UID is not "1.2.840.10008.5.1.4.1.1.128.1" (Legacy Converted). May be present otherwise. |
|||
Describes the approximate lossy compression ratio(s) that have been applied to this image. |
|||
A label for the lossy compression method(s) that have been applied to this image. |
|||
Specifies an identity transformation for the Presentation LUT, such that the output of all grayscale transformations defined in the IOD containing this Module are defined to be P-Values. |
|||
See Section C.7.6.1.1.6 for further explanation. |
|||
Include Table C.36.2.4.12-1 “RT Equipment Mapping and Plan Reference Macro Attributes” |
The Image Type Attribute (0008,0008) and Frame Type (0008,9007) identifies important image characteristics in a multiple valued Data Element. In addition to the requirements specified in Section C.8.16.1 Image Type and Frame Type, the following additional requirements and Defined Terms are specified:
Value 1 of Image Type (0008,0008) and Frame Type (0008,9007) is discussed in Section C.8.16.1.1. No additional requirements or Defined Terms.
Value 2 of Image Type (0008,0008) and Frame Type (0008,9007) is discussed in Section C.8.16.1.2. No additional requirements or Defined Terms.
Value 3 of Image Type (0008,0008) and Frame Type (0008,9007) is discussed in Section C.8.16.1.3. No additional requirements or Defined Terms.
Value 4 of Image Type (0008,0008) and Frame Type (0008,9007) is discussed in Section C.8.16.1.4. No additional requirements or Defined Terms.
The Attribute Attenuation Correction Source (0018,9738) contains the source of the attenuation map information used for attenuation correction.
The Attribute Attenuation Correction Temporal Relationship (0018,9770) specifies the temporal relationship between the attenuation correction source image and the PET image data.
Defined Terms:
The attenuation correction source image is acquired at approximately the same time and with the patient in the same body position as the PET image; for example, as acquired on a hybrid scanner
The attenuation correction source image is acquired at a different time, on a different system, or the patient has been moved significantly enough to cause soft tissue movement; for example, an attenuation correction source image acquired on a separate CT scanner, so that the patient must move from one bed to another
The attenuation correction source image is acquired at the same time and with the patient in the same body position as the PET image
