Section C.8.9.4.1.4
C.8.9.4.1.4 Acquisition Date, Acquisition Time
For PET Images, Acquisition Date (0008,0022) and Acquisition Time (0008,0032) are specified to be Type 2. Acquisition Date (0008,0022) and Acquisition Time (0008,0032) use the same time base as Series Time (0008,0031).
For Series Type (0054,1000) Value 1 equal to STATIC, WHOLE BODY, or DYNAMIC, Acquisition Time (0008,0032) is the real-world beginning of the accumulation of events into this Image. For STATIC, WHOLE BODY, or DYNAMIC Series, Acquisition Time (0008,0032) may vary from Image to Image within a PET Series.
For Series Type (0054,1000) Value 1 equal to GATED, Acquisition Time (0008,0032) is the real-world beginning of the capability of accumulating events into this Image. (The actual accumulation of events has only occurred during an R-R Interval.) For GATED Series, Acquisition Time (0008,0032) shall not vary from Image to Image within a PET Series.
