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.
