These data elements aremarked as Copy from the original SOP Instance in Table 8-1. These data elements provide theoriginal pixel data context from that the thumbnail has been derived. Note that they do not contain thevalues specific to the thumbnail.The GE Private Image Thumbnail Sequence uses a number of standard data elements to describe theproperties of the thumbnail pixel data. Note that these data elements in this sequence really contain thevalues specific to the thumbnail, but not to the original image pixel data.8–65
