A novel representation of the MPI system function

Abstract

In a recent publication, based on the Langevin model, the exact mathematical relationship between the system function and tensor products of Chebyshev polynomials of second kind has been derived for the case in which multidimensional excitation is used for magnetic particle imaging. There, a new expression for the system function in magnetic particle imaging was derived. To make this representation easily accessible, the present paper focusses on the more practical aspects of the theory without going deep into the mathematical proofs. In particular, we examine the contribution of the mixing factors to the total energy of a system function component.
