迭代自适应加权滤波反投影（FBP）方法被应用于我们的光声成像（PAI），该成像来自有限视图数据的生物组织中的光学吸收。通过使用基于图像的自适应加权 PAI 重建，我们可以修改降低图像质量的伪影缺陷。数值模拟结果表明，该算法在精度和噪声鲁棒性方面均优于FBP。生物组织的重建图像与样本的结构非常吻合。实验证明采用该方法的 PAI 系统的分辨率优于 0.14 mm。通过使用所提出的方法，可以提高PAI系统的成像质量。 (C) 2013 美国光学学会
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
