> From the bubble center plot, I'm guessing that the bubbles are separated on average about a few mm apart?

The page is vague so I can't tell. I think the images they're showing are actually a composite of many bubbles tracked through the vasculature.

They say this:

> As bubbles flow through the vasculature, we accumulate millions of these positions and stack them into a single image with detail finer than the wavelength.

And the rendering showing the bubble centers they're tracking only shows a few small points moving at a time.

I think that the amazing animation they produced at the top is actually a composite of many different trackings, not an actual representation of what they capture in real-time.
