Abstract
We present a preliminary study on the design of a small animal positron emission tomograph with octagonal
geometry. The main goal is to evaluate the impact of critical
design parameters on the quality of the reconstructed images.
Monte Carlo simulations take into account the depth of
interaction in individual crystals. The activity sources are
simulated as parametric distributions within the field of view and
images are reconstructed with iterative algorithms based on the
estimation of maximum likelihood and Bayesian regularization.
The probability system matrix used by these algorithms is also
calculated based on statistical models and Monte Carlo
simulation. 2D and 3D techniques have been employed.
