Channel Source Sequence Attribute

Tag(003A,0208)
TypeRequired (1)
KeywordChannelSourceSequence
Value Multiplicity1
Value RepresentationSequence (SQ)

A coded descriptor of the waveform channel source (metric, anatomical position, function, and technique).

Only a single Item shall be included in this Sequence.

(see Section C.10.9.1.4.1)

Section C.10.9.1.4.1

C.10.9.1.4.1 Channel Source and Modifiers

Channel Source Sequence (003A,0208) identifies the metric (quality being measured, e.g., voltage or pressure), the anatomical position of the sensor or probe, the function of the channel (e.g., measurement or stimulus), and any particulars of technique that affect those parameters (e.g., pull-back across multiple anatomic sites, or differential input from two distinct sites). If the full semantics of the source is not carried in a single coded entry (e.g., if it specifies the location but not the metric), additional qualifiers are identified in Channel Source Modifiers Sequence (003A,0209) coded entries.

When a single sensor channel is used to collect a waveform from two (or more) anatomic sites, e.g., in hemodynamic pull-back procedures, multiple Channel Source Modifier Items will identify the sequence of sites, if not encoded in the semantics of the Channel Source Coded Entry. Transition times from one site to another may be indicated with an Annotation, or pull-back rate may be indicated with an Acquisition Context Sequence (0040,0555) Item (see Section C.7.6.14).

The Baseline CIDs are defined by IOD in accordance with Section A.34. Restrictions in the IOD may also determine the pattern of specification of the waveform source, i.e., which Item is to be encoded in the Channel Source Sequence, and the order in which Channel Source Modifier Items are to be encoded. Unless otherwise specified, pattern of specification of the waveform source shall be:

  1. If the function of the channel is not measurement, the function (and optionally additional parameters of the channel source) shall be encoded in the Channel Source Item.

  2. If the function of the channel is measurement of a waveform originating in the patient (the implicit default function), the metric (and optionally additional parameters of the channel source) shall be encoded in the Channel Source Item.

  3. If not encoded in the Channel Source Item, and a particular technique needs to be encoded, that technique shall be encoded in the first Channel Source Modifier Item.

Note

For example, an intracardiac measurement of a pressure waveform across the mitral valve by means of a catheter pullback may be encoded in one of the following three ways (using pseudo-coded terminology), depending on the availability of coded terms with sufficient expressive power:

Channel Source

Channel Source Modifiers

X-2311 "pressure measurement"

T-7663 "pullback"C-2001 "mitral valve"

X-2123 "pressure measurement, pullback"

C-2001 "mitral valve"

X-1234 "pressure measurement, mitral valve, pullback"
