The reconstruction results of the human head slice by ADSIR with different regularization parameter. a–c The image reconstructed by 180 scanning views data with no noise; d–f the difference between the reconstructed image (a–c) and the original image (OI); g–i the image reconstructed by 180 scanning views data simulated by 2 million photons; j–l the difference between the reconstructed image (g–i) and the original image (OI). The first to third columns refer to the results with λ, 0.2λ and 5λ respectively
