We assume simple boundary conditions and remove the background field by explicitly solving the boundary value problems of Laplaces or Poissons equation. The proposed Laplacian boundary value (LBV) method for background field removal retains data near the boundary and is computationally efficient. Tests on a numerical phantom, an experimental phantom and in in vivo data sets showed that LBV was more effective than the SHARP and PDF methods.
