Vlad, The most natural way to do this would be to create your own version of SegmentAnnotator. Most cTAKES components iterate over Segment annotations and process text in each segment. So if you create an annotator that annotates the IMPRESSION section as the only segment that will be the only text that gets processed by subsequent annotators.

Of course, one can go and parse out this section only in a new document and do it this way but with millions of such notes the cleaner way would be to instruct ctakes to only process a specific section.
