Thank you.
Certainly there is a network of PET isotope generators and cyclotron centres in the U.S. That is a robust network and it does supply a lot of the clinical demand.
What we envision...and this is part of a national discussion. TRIUMF had 16 major medical centres attend a conference in October 2007, where we actually discussed this topic of how you could put up a national network to coordinate development of isotopes, to share the clinical expertise, and to provide a coordinated clinical trials platform for new products.
The role that TRIUMF has is really as a research and development leader. We actually have expertise in all of the areas. Our view is that over the next 10 years it's fairly likely that Canada will move to a network of PET isotope producers. In fact, we're developing something we call the “espresso-maker”. It would be isotope on demand, single-patient doses that would be placed in every hospital for under a million dollars. That's certainly the direction we see the country headed. It's not going to be here tomorrow and it's not going to be here the day after that.
