Is there a link between conventional Quantum Mechanics and QFT?

Possible Duplicate:
Is there a theorem that says that QFT reduces to QM in a suitable limit? A theorem similar to Ehrenfest's theorem?

Just as Quantum Mechanics is related to Classical Mechanics via Ehrenfest's Theorem, Is there a theoretical link between say, the free scalar field theory and Schroedinger's Equation?

What about QFT theories with spin?

Comparing Quantum Field Theory with Quantum Mechanics is a little like comparing an english poem with the english language.
