Table 1 Considerations for implementing different gating strategies

	Hardware-driven strategies	Data-driven gating
Requires changes to clinical image acquisition procedures	x
Requires additional hardware	x
Requires additional software	x	x
Requires additional setup time	x
Prone to setup error	x
Information irrecoverable if acquisition error	x
Decreases clinical throughput	x
Requires additional training of technologists	x
Increases radiation exposure to technologists	x
May cause patient discomfort	x
Require further establishment before routine clinical use	x	x
Reproducible		✓
Operator independent		✓
Can be acquired and reacquired from an existing data set (if needed)		✓
Non-specific to scan/machine/institution		✓
Driven with internal motion		✓
