Yes, it's very important, in the sense that in the heat of the COVID-19 crisis, our capacity to operate our unit as before was decreased. For one unit, let's say, we were able to do 80 patients a day. Now we are doing 60 patients a day. We are not sure it will change in the short term, because of the issue raised by Dr. Liu that we may have a second hit coming. Also, other infections can change. I believe that, for all high-throughput procedures, we need to change the way we are doing them.
We have two ways to increase our capacity. The first is to further capital investment, as raised by Dr. Barry, to increase the number of units, because we cannot do the same amount as before. In Canada, we have the most productive radiologists for one unit, compared to the U.S. There's a really big difference. The second is to extend the operation time. It means that we need more personnel, more resources. Third, in all the waiting rooms we need to install...to be sure we are safe. We have some really important measures to do.
Mike, perhaps you want to comment on that.
