Hi Jin,
assuming you have a binary image with the red being the foreground, you
could try dilation until the gap becomes a hole, then 'Fill Holes' and
erosion (a bit more erosion than dilation). Then merge with the original.
For dilation and erosion I'd use the Process>Filters>Maximum & Minimum
filters; these have a circular structuring element (the binary
operations have a square one).
Unfortunately, this procedure will also connect the left lung with the
extra particle next to it; I see no way to avoid this.
Michael
