C. Waveform Originality

Waveform Originality (003A,0004) shall have the value ORIGINAL if the Waveform Data samples are the original or source data, and shall have the value DERIVED if the Waveform Data samples have been derived in some manner from the sample data of other waveforms.

Notes : 1. The Waveform Originality (003A,0004) attribute is comparable to the Image Type (0008,0008) attribute value 1 (see C. Within a single Multiplex Group, all channels shall have the same Originality value.

2. Waveform data which has been transcoded from a non-DICOM format may have Waveform Originality value ORIGINAL if the samples are unchanged from the originally acquired waveform samples.
