Type |
Attribute Description |
|---|---|---|---|
|
Complex Image Component |
(0008,9208) |
1C |
Representation of complex data of frames in the SOP Instance. See Section C.8.13.3.1.1 for a description and Defined Terms. Required if SOP Class UID is not "1.2.840.10008.5.1.4.1.1.4.4" (Legacy Converted). May be present otherwise. |
|
Acquisition Contrast |
(0008,9209) |
1C |
Indication of acquisition contrast used with frames in the SOP Instance. See Section C.8.13.3.1.2 for a description and Defined Terms. Required if SOP Class UID is not "1.2.840.10008.5.1.4.1.1.4.4" (Legacy Converted). May be present otherwise. |
The value of Complex Image Component attribute (0008,9208) shall be used to indicate which component of the complex representation of the signal is represented in the pixel data.
Table C.8-85 specifies the Defined Terms for Complex Image Component (0008,9208).
Table C.8-85. Complex Image Component Attribute Values
|
Defined Term Name |
Defined Term Description |
|---|---|
|
MAGNITUDE |
The magnitude component of the complex image data. |
|
PHASE |
The phase component of the complex image data. |
|
REAL |
The real component of the complex image data. |
|
IMAGINARY |
The imaginary component of the complex image data. |
|
MIXED |
Used only as a value in Complex Image Component (0008,9208) in the Enhanced MR Image Module if frames within the image SOP Instance contain different values for the Complex Image Component attribute in the MR Frame Type Functional Group. |
Table C.8-86 specifies the Defined Terms for Acquisition Contrast (0008,9209).
Table C.8-86. Acquisition Contrast Values
|
Defined Term Name |
Defined Term Description |
|---|---|
|
DIFFUSION |
Diffusion weighted contrast |
|
FLOW_ENCODED |
Flow Encoded contrast |
|
FLUID_ATTENUATED |
Fluid Attenuated T2 weighted contrast |
|
PERFUSION |
Perfusion weighted contrast |
|
PROTON_DENSITY |
Proton Density weighted contrast |
|
STIR |
Short Tau Inversion Recovery |
|
TAGGING |
Superposition of thin saturation bands onto image |
|
T1 |
T1 weighted contrast |
|
T2 |
T2 weighted contrast |
|
T2_STAR |
T2* weighted contrast |
|
TOF |
Time Of Flight weighted contrast |
|
UNKNOWN |
Value should be UNKNOWN if acquisition contrasts were combined resulting in an unknown contrast. Also this value should be used when the contrast is not known. |
|
MIXED |
Used only as a value in Acquisition Contrast (0008,9209) attribute in the Enhanced MR Image Type Module if frames within the image SOP Instance contain different values for the Acquisition Contrast attribute in the MR Frame Type Functional Group. |
