Simulated data. Synthetic ground truth and top/bottom simulations. (a) solid sphere with smooth random texture added to attenuations and intensities (well-posed reconstruction problem). Intensity range: [0, 8500], attenuation range: [0, 0.012]; (b) Shepp-Logan phantom with large constant areas (ill-posed reconstruction problem). Intensity range: [0, 65535], attenuation range: [0, 0.01]. All views show the central xy-, xz-, and zy-sections of the corresponding 3D volumes. Each panel shows: First row: ground truth intensities I (left) and absorption coefficients α (right). Second/third row: confocal simulations from top/bottom; Noise free (left); with applied Poisson-Gaussian noise (right) (m=0.05, σ=10. The rmse compared to the noise free simulation is indicated).
