摘要：
An expression is derived for the electron density resolution of proton computed tomography obtained from algebraic reconstruction methods. The dependence of the resolution on system parameters is clarified and methods for achieving the best resolutions possible are suggested. Comparison of our results with previous ones from the literature is included as well as a discussion of the limitations of the results.
