The only person who won't have to go through a backscatter scanner at most airports, especially smaller ones, is someone with an infant in arms.
So it depends on where you're coming from. I don't think I go through backscatter at LAX, but I do at BWI, BDL, ATL, TYS, BOS. What is your departing airport?
The TSA has pulled the Rapiscan "backscatter" x-ray machines from U.S. airports earlier this year. The controversial devices used x-rays to produce "naked" body scans viewed by a TSA screener (out of view of the public). There were objections due to the use of x-rays and due to privacy concerns.
The TSA has replaced the backscatter machines with millimeter wave scanners. These use radio waves, not x-rays. The millimeter wave scanners reveal anomies (which could be weapons), not full body images.
The experience of going into backscatter and millimeter wave machines is similar. You stand in one spot with raised arms for five seconds. I'm sure many people are unaware they're two different technologies and that the backscatter machines are gone.
This has been my experience also. Kids travelling with you = "normal" xray machine. They may send one adult through the 'big' machine, but we've been able to stay with our family.
Nobody goes through an x-ray machines.
There are the traditional magnetometers (electromagnetic, walk-through metal detectors) and the millimeter wave scanners. Neither uses x-rays.
The TSA agent determines which one you go through.
