8. Thought Experiment or Practical Plan: We wonder whether you see this as just a thought experiment at this point, or are you thinking that people should actually institute some kind of cash incentive to reduce CT use? Where would the $100 come from? I imagine getting a patient out of the hospital earlier, and freeing up their stretcher, might actually generate more than the $100 needed to incentivize them not having the scan. Have you thought about the overall economics of this model?
