They haven't shared enough to say anything concrete, but one important detail is that this system doesn't have many of the benefits usually found in ultrasound (portable, cheap, simple). From what they've shared, it's a large water bath that patients need to be submerged in with a large array of US sensors with high costs in data and reconstruction compute. It might have lower upfront cost, but otherwise, I personally don't see the advantages yet. A typical MRI can be done is under 30 minutes in street clothes, and personally I'd rather not deal with the logistics of a water bath...

There are huge backlogs of folks for imaging... Radiologists aren't exactly sitting around daydreaming all day waiting for a patient.
