Exponentially would make it computationally intractable by definition, and is the proposal suggestion that having simultaneous sensors can be used to reconstruct more information than the conventional way of using a handheld single sensor? Is that plausible?
Good question. Trying to 'steel-man' MJ's approach, that was the only possible benefit vs the existing Butterfly product which I hadn't crossed out yet, so I asked the only actual radiologist here about the possibility of having additional receivers off-axis from the emitter (https://news.ycombinator.com/item?id=48590631).
But frankly, I'm losing interest trying to glean what someone might be thinking, when they're being so intentionally opaque while making such grandiose vague claims. The bottom line is, if they really thought this way of nerfing Butterfly's chip '9-steps back' with disadvantages, would truly unlock 12-steps forward in actual medical imaging utility, they wouldn't be launching it as a 'feature' of a vanity spa with nothing but vague 'tech visionary' puffery.
