How to detect intersection in a skeleton image?

I got a skeleton from a laser grid. So, there are a lot of spur things, but after "cleaning" I got a "nice" skeleton of my laser grid.

There is a way to detect all the cross points (the nodes)? I'm looking for somethings more stronger than 'branch points' or 'majority' of bwmorph function..

my image is that attached
