An　iterative　adaptive　weighted　filtered　backprojection　(FBP)　approach　was　applied　to　our　photoacoustic　imaging　(PAI)　of　the　optical　absorption　in　biological　tissues　from　limited-view　data.　By　using　an　image-based　adaptive　weighted　PAI　reconstruction,　we　can　modify　the　defect　of　the　artifacts　degrading　the　quality　of　the　image.　Results　of　numerical　simulations　demonstrated　that　the　proposed　algorithm　was　superior　to　FBP　in　terms　of　both　accuracy　and　robustness　to　noise.　Reconstructed　images　of　biological　tissues　agreed　well　with　the　structures　of　the　samples.　The　resolution　of　the　PAI　system　with　the　proposed　method　was　experimentally　demonstrated　to　be　better　than　0.14　mm.　By　using　the　proposed　method,　the　imaging　quality　of　the　PAI　system　can　be　improved.　(C)　2013　Optical　Society　of　America
