A magnetic particle imaging (MPI) measurement method includes generating a multi-dimensional image-domain system matrix A using an MPI-sequence with a field free line, using a multi-dimensional sinogram-based system matrix A Sinogram ( t , r , z ) ∈ ℝ [ T , N r , N z ] , comprising the following steps: for each time point tc, c∈[1, T]: get a time slice matrix Ac=ASinogram(t=tc, r, z)∈[Nr,Nz], replicate the time slice matrix Ac Nr−1 times and copying these replications along a newly added 2nd offset-dimension, resulting in a time volume matrix A c ′ ∈ ℝ [ N r , N r , N z ] , rotate the time volume matrix A c ′ by the FFL θc=θ(t=tc) at time point t=tc in its 1st and 2nd offset-dimensions, resulting in a rotated matrix A c θ c concatenate the rotated matrices A c θ c of all time points along a time-dimension and vectorize the spatial dimensions (x, y, z), resulting in a constructed system matrix cSM∈[T,(Nr×Nr×Nz)], and perform a Fourier transformation on the constructed system matrix cSM on its time-dimension resulting in the multi-dimensional image-domain system matrix A.
