1 - There's been discussion about the scanner not having as much radiation as a CT Scanner. I cannot get a CT Scan, because I have a pacemaker. Am I therefore unable to go through these scanners? Are there magnets used in there? My Pacemaker CAN go thru the metal detector due to the manner in which ot is shielded. It does not set off the detector.

2 - If these scanners can see thru clothing, how come we have to take our shoes off?????
