This work is focussed on a comparison between two methods based in the target ﬁeld method (TGM) to design Shielded Gradient coils for MRI. The main problem of the TGM is that a current of inﬁnite extent is designed with a set of constraints but the current is modiﬁed, and in consequence the ﬁnal coil might not have the desired characteristics. Carlson proposed a current distribution using a Fourier Series for a coil of ﬁnite length. Another solution was proposed by Chronik that adds a set of current constraints forcing the current to lie over a certain length.
