Estimate of FDG Excretion by means of Compartmental Analysis and Ant Colony Optimization of Nuclear Medicine Data

Figure 2

Simulated experiment with a full matrix 𝐀 as in (4). Results obtained with the following ACO parameters: 𝑃=13, 𝑄=7, 𝑞=0.015, and 𝜉=0.4 for 30 runs of the algorithm. (a) Red line represents 𝐶_𝑏, green line represents 𝐶_𝑢, and blue line represents the total measurement on kidneys. In black, the same data corrupted by Poisson noise. (b) Superimposition of synthetic data (white dots) and reconstructed confidence strips of concentrations.
