One challenge ahead--in most hospitals, the doctors have to choose to use these new tools and many aren&#x27;t.   Some don&#x27;t see the need (maybe due to a generally conservative attitude), and others actually see them as a liability (if there&#x27;s more data than they can personally review, they could be sued for missing an important signal).  But at least the research hospitals are making headway in developing and testing new tech.
