I really don't understand why a fetus' heart can be examined for defects, but you can't use it in the office to tell me if my labrum is torn?
Ignoring all of this, there are few sub specialist radiologists in the world who could theoretically do this and if you were to pay for their time it would cost more than a highly reproducible and easy to get MRI.
But high resolution imaging of blood flow? That's a pretty great medical diagnostic tool if you can make it more available and cheaper.

Combined with ultrasound, could these be causing damage of any kind to the vasculature?

How realistically close can this get to reading thoughts, visuals, etc.?
Do we have a path to imaging people's visual cortex? Their inner lives, dialogues, memories? (Scary thought - this could be used as an interrogation tool without consent. "Did you kill Bob?" could be a simple brain scan.)
Can it be done in real time in a feedback loop and perhaps be used as an advanced reinforcement learning system?
That's bad enough in democracies, but the consequences in more common forms of government seem really dystopian.
Edit: wow, serves me right for asking / not understanding that contrast means SF6...
