Comments

This function sets the channel source. Before calling this function, initialize pChannelSource> uStructSize to be sizeof(DICOMCODESEQUENCEITEM) and initialize all the members of the structure.

In DICOM it is mandatory to specify the source for a channel. Therefore, it is important to call this function to create a proper waveform channel. For more information about a waveform channel source, please refer to "Channel Source Sequence" (003A, 0208) in the DICOM standard.

To fill the members of the pChannelSource structure you can use the functions offered by the context groups functions (L_DicomxxxContextGroup and L_DicomxxxCodedConcept). For more information about these functions and the use of Coded Concepts in DICOM, please refer to Working with Context Groups.
