Claim One:
1. Method of improving the resolution of SPECT imaging of a target region of a biological object comprising: simultaneously performing MRI and SPECT imaging to identify a limited field of view (LFOV) which includes a region of interest; generating average intensities for the region of interest and a region outside the region-of-interest; generating an adaptive system matrix defined by S i , j ′ = ∑ k S i , k ξ k , j where ( 1 ) ξ k , j = { T / B if ( k , j ) ∈ target 1 if ( k , j ) ∈ LFOV ⋂ target c … 0 if ( k , j ) ∈ LFOV c ( 2 ) where Si,j is the system matrix, and where the elements of the weighting matrix, ξ k,j , within the LFOV, where target c is a region outside the target region and where LFOV c is a region outside the LFOV; and generating an image of the region of interest in the LFOV using the adaptive system matrix.
