Half baked images? No one said that is impossible.

I am skeptical of any brain ultrasound claim that doesn’t use skull correction which requires a CT scan.

Very large chunks of vasculature and major arteries are missing in the images they provided. Just because it’s pretty and colorful it doesn’t mean it’s useful.

Perhaps it will one day, but this doesn’t prove much so far. There are several physical challenges to using ultrasound.
