This is an interesting question! I’ve never personally seen anything intentionally for solving this - but I’m curious what your angle is. Are you looking for a solution to your problem by seeking a relevant problem/solution in the other field? Or potentially looking for product/market fit in other fields? Richard Feynman touches on this a bit when he starts doing some work related to biology (iirc). As an individual id recommend gaining a broad exposure to different fields whenever possible. Maybe websites like phys.Org (science news aggregator) or big journals like Nature/Science could help (thinking specifically Review articles rather than research publications). Also if you have any exposure to a research institution getting to know graduate students could possibly help (easier said than done!) Lastly, I personally have the impression that the field of neuroscience is very broad and may be of relevance/interest to you. There is a lot of computation involved and people draw from diverse academic backgrounds - wouldn’t be surprised if ultrasound is used in neuroscience research but not sure (I am not a neuroscientist but my SO is) Addendum: I’m not a Twitter user but perhaps “science Twitter” could help you gain exposure to problems being faced in other fields. Good luck
