Does Ultrasound Work for Cellulite?

I've been reading a lot about cellulite recently, and I'm trying to understand it better. What do you think about using ultrasound for cellulite? If indeed the main cause of cellulite is reduced circulation (caused by enlarged fat cells), then, does it make sense to use ultrasound on areas where fat deposits?

From what I have read on physiotherapy sites, ultrasound machines promote healthy circulation and tissue conditions by venous stimulation, so it improves tissue vascularisation. I know their main purpose is for muscle injury, however. I have seen (through web searches) that some clinics are using Ultrasound for cellulite, but it doesn't get much publicity and is not as common as procedures like Endermologie or Lipodissolve. So, I'm wondering, what do the experts on this site think? Thanks for your time.
