Actually, I never understood this. Is demand and supply matched and this is just the lag in the system (ie 6-8 weeks remains 6-8 weeks forever) or demand is greater than supply and this number will grow. If it is the former then there doesn't seem to be a cost advantage for the wait. A temporary increase in supply could bring this waiting time to zero with just the cost of 6-8 weeks worth of x-rays outsourced. And then you have a steady state system with zero waiting.
