Pixel Presentation

(0008,9205)

Set to "TRUE_COLOR"

Presentation State Classification Component Sequence

(0070,1801)

Contains two items, one for each classification component.

>ITEM 1

>Component Type

(0070,1802)

Set to "ONE_TO_RGBA"

>Component Input Sequence

(0070,1803)

Only one item in this sequence since the component has only one input.

>>Input Set Index

(0070,1804)

Set to "1" for the MPR slice of the TISSUE_INTENSITY data

>RGB LUT Transfer Function

(0028,140F)

Set to "EQUAL_RGB" to map to grayscale RGB values.

>Alpha LUT Transfer Function

(0028,1410)

Set to "IDENTITY"

>ITEM 2

>Component Type

(0070,1802)

Set to "ONE_TO_RGBA"

>Component Input Sequence

(0070,1803)

Only one item in this sequence since the component has only one input.

>>Input Set Index

(0070,1804)

Set to "2" for the MPR slice of the FLOW_VELOCITY data

>RGB LUT Transfer Function

(0028,140F)

Set to "TABLE" to be able to map to colors representing the flow velocities towards and away from the ultrasound transducer

>Alpha LUT Transfer Function

(0028,1410)

Set to "IDENTITY"

…

Definitions of lookup tables left out for brevity.

Presentation State Compositor Component Sequence

(0070,1805)

Set to one item that defines the threshold compositing of the two data types

>Weighting Transfer Function Sequence

(0070,1806)

Contains the two Weighting LUTs from Section XXX.5.4 to create the threshold composting from two RGBA inputs:

  • If the magnitude of the FLOW_VELOCITY input is greater than the magnitude of the TISSUE_INTENSITY input, display the MPR of the FLOW_VELOCITY data.

  • Otherwise, display the MPR of the TISSUE_INTENSITY data

…

Definitions of lookup tables left out for brevity.

ICC Profile

(0028,2000)

Set to an ICC Profile describing the transformation of the resulting RGB image into PCS-Values.
