You might check ImageJ from the US NIH for a free solution. If I recall correctly it has reasonable ROI tools.
Alternately, the AnalyzeAVW product has a poorly named but quite functional "Line Tool" that I would expect to meet your needs. Analyze is, however, far from free -- single node academic license is about US$5k. Yet another option: you could use MRIcro, export as a Analyze7.5 and write something to harvest the non-zero pixel positions. The Analyze7.5 format is well known and readily found in a google search. There are many publicly available libraries that provide i/o in that format.
