##### C.8.8.2.8 Exposure Time and Meterset Exposure

Multi-frame RT Images may encode a continuous acquisition. In this case, the Exposure Sequence (3002,0030) may not reference all frames.

The Attributes Exposure Time (00018,1150), Exposure Time in ms (0018,9328) and Meterset Exposure (3002,0032) Attributes in the Exposure Sequence (3002,0030), if present with values, contain the exposure values encompassing the X-Ray exposure during the acquisition of the single frame referenced by the Referenced Frame Number (0008,1160). Note that not all frames may be referenced in this Sequence and therefore the sum of these values may not equal the total exposure value.

The Attributes Exposure Time (00018,1150), Exposure Time in ms (0018,9328) and Meterset Exposure (3002,0032) Attributes outside the Exposure Sequence (3002,0030) may be used to record the total exposure values.
