Mental Wanderings - Transporting

I have a dilemma which I hope a Trekkie can solve for me. In the act of transporting, one's body is transformed into an energy pattern (dematerialization), sent to a target, and then changed back into matter (rematerialization). Does this process not mean that an individual is, in essence, annihilated and then reformed? And if this is the case, is the individual not therefore killed by the act of dematerialization and a new individual, identical to the first, created on the other end?
Just wondering . . .
