  • Title: A method for the design of MRI radiofrequency coils based on triangular and pulse basis functions.
    Author: Yau D, Lawrence B, Crozier S.
    Journal: MAGMA; 2002 Jan; 13(3):145-51. PubMed ID: 11755089.
    Abstract:
    This paper presents a numerical technique for the design of an RF coil for asymmetric magnetic resonance imaging (MRI) systems. The formulation is based on an inverse approach where the cylindrical surface currents are expressed in terms of a combination of sub-domain basis functions: triangular and pulse functions. With the homogeneous transverse magnetic field specified in a spherical region, a functional method is applied to obtain the unknown current coefficients. The current distribution is then transformed to a conductor pattern by use of a stream function technique. Preliminary MR images acquired using a prototype RF coil are presented and validate the design method.
