Positron kinetics in an idealized PET environment

Robson, Robert E.; Brunger, Michael J; Buckman, Stephen; Garcia, Gustavo; Petrovic, Z Lj; White, R D


The kinetic theory of non-relativistic positrons in an idealized positron emission tomography PET environment is developed by solving the Boltzmann equation, allowing for coherent and incoherent elastic, inelastic, ionizing and annihilating collisions through positronium formation. An analytic expression is obtained for the positronium formation rate, as a function of distance from a spherical source, in terms of the solutions of the general kinetic eigenvalue problem. Numerical estimates of...[Show more]
