C.39.4 Displayed Waveform Segment Module

This Module defines Attributes required to define waveform segments and the properties how to display them. A waveform segment is a temporal portion of a waveform ("segment of interest").

Attribute Description

Displayed Waveform Segment Sequence

(0040,B035)

1

Selects and provides display parameters for segments from a group of waveforms or channels within these waveforms.

One or more Items shall be included in this Sequence.

>Segment Definition DateTime

(0040,B036)

3

The date and time the segment was defined.

>Referenced Waveform Sequence

(0008,113A)

1C

The waveforms to which the segment display parameters in this Item apply.

One or more Items shall be included in this Sequence.

Required if the segment display parameters in this Item do not apply to all the waveforms and channels contained in Referenced Waveform Sequence (0008,113A) in the Referenced Series Sequence (0008,1115).

>>Include Table 10-11 “SOP Instance Reference Macro Attributes”

This references waveforms to which the segment display parameters in this Item apply.

The Instances referenced here shall be contained in the Referenced Waveform Sequence (0008,113A) in the Referenced Series Sequence (0008,1115).

>>Referenced Waveform Channels

(0040,A0B0)

1

Identifies the waveform multiplex group (M) and channels (C) within the referenced SOP Instance using pairs of values (M,C).

See Section C.10.10.1.1.

>Include Table C.39.8-1 “Temporal Range Macro Attributes”

Enumerated Values for Temporal Range Type (0040,A130):

>Waveform Display Background CIELab Value

(003A,0231)

1C

A color triplet value recommended for rendering the waveform display background on a color display. The units are specified in PCS-Values, and the value is encoded as CIELab. See Section C.10.7.1.1.

Required if Channel Recommended Display CIELab Value (003A,0244) is not present. May be present otherwise.

>Channel Recommended Display CIELab Value

(003A,0244)

1C

A color triplet value recommended for rendering the channel on a color display. The units are specified in PCS-Values, and the value is encoded as CIELab. See Section C.10.7.1.1.

Required if Waveform Display Background CIELab Value (003A,0231) is not present. May be present otherwise.
