C.8.22.2.1 Enhanced PET Acquisition Module Attribute Descriptions

C.8.22.2.1.1 Acquisition Start Condition

Acquisition Start Condition (0018,0073) is the method of starting acquisition data collection. The Defined Terms and definitions are:

DENS = preset count density (counts/sec) was reached

RDD = preset relative count density difference (change in counts/sec) was reached

MANU = acquisition was started manually

AUTO = start automatically, when ready

CARD_TRIG = preset number of cardiac triggers was reached

RESP_TRIG = preset number of respiratory triggers was reached.

C.8.22.2.1.2 Acquisition Termination Condition

Acquisition Termination Condition (0018,0071) is the method of acquisition termination which has actually applied to the data collection. The Defined Terms and definitions are:

CNTS = preset counts was reached.

DENS = preset count density (counts/sec) was reached

RDD = preset relative count density difference (change in counts/sec) was reached

MANU = acquisition was terminated manually

OVFL = data overflow occurred.

TIME = preset time limit was reached

CARD_TRIG = preset number of cardiac triggers was reached

RESP_TRIG = preset number of respiratory triggers was reached

C.8.22.2.1.3 Energy Window Range Sequence

Multiple energy windows are allowed in order to allow coincidence events based on additional Energy Windows (e.g. Compton events scattered in the detector). All energy windows are assumed to contribute to all frames in this image.
