Registration of Pencil Beam Proton Radiography Data With X-Ray CT.

CONCLUSIONS: For registration of proton radiography data with X-ray CT, the use of a direct ray-tracing algorithm to compute sums of squared differences and corrections of range errors showed very good accuracy and robustness with respect to three confounding factors: measurement noise, calibration error and spot spacing. It is therefore a suitable algorithm to use in the in vivo range verification framework, allowing to separate in post processing the proton range uncertainty due to set-up errors from the other sources of uncertainty.
