Images reconstructed from non-attenuated data contaminated with Gaussian random noise. Images (a-c) were reconstructed by use of the WISE method with a quadratic penalty with βQ = 1.0×10−3, 1.0×10−2, and 1.0×10−1, respectively. Image (d) was reconstructed by use of the WISE method with a TV penalty with βTV=5.0×10−4. The insert in the up right corner of each image is the zoomed-in image of the dashed black box, which contains 35×35 pixels (17.5×17.5mm2). The grayscale window is [1.46,1.58] mm/μs.
