The "hot spots" are set off by any difference. Unfortunately if you are a bigger person it is very easy to set these machines off (not saying the OP is bigger just the general you). Also for me it is my shoulder blades. Every single time the middle of my back sets off. The reason being when I put my hands over my head like they require my shoulder blades don't sit flat like they should. I try to adjust but 99% of the time when I go through TSA I forget to adjust to better posture and so they poke out a little setting off the machine.
