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.
