Method for Reconstructing Volume Density Distribution in Dynamic Targets in Proton Radiography Experiments

A method for reconstruction of the volume density distribution in dynamic targets from their proton radiography image is considered. The reconstruction can be carried out using the inverse Abel transform under the assumption that the studied object and processes have radial symmetry. To increase the accuracy of reconstructed data, algorithms for correction of basic types of distortions of proton radiography images are proposed. The results of processing experimental data obtained on proton radiography facilities PUMA at ITEP and PRIOR at GSI are presented.
