A needle guide system comprises a base adapted for non-pivotal connection to
an
imaging device, an arm pivotally connected to the base, and a needle guide pivotally
connected to the arm at a point distal from the arm-base connection. The needle
guide is adapted to receive at least one needle. The length of the arm extending
between the base and the needle guide is adjustable. Methods for positioning a
needle relative to an imaging device employ the needle guide system.
