Comparison of proton beam depth dose curve in water obtained using a Markus chamber in water tank with that obtained using MatriXX in plastic water phantom without and with buildup material thickness correction.
Linearity test for the response of MatriXX central detectors ( arrays) to delivered dose.
Comparison of proton beam profiles measured simultaneously at depths of 23.1 and using film dosimetry and MatriXX, respectively.
Measured dose per for different proton energy using MatriXX central chamber arrays. The measured doses are scaled by dividing the relative output factors (ROF) that were measured using a Farmer chamber as part of a clinical commissioning process.
Comparison of proton beam flatness and symmetry measured using a PTW Pinpoint ionization chamber in a water tank and the MatriXX ion chamber array.
A typical set of measured flatness and symmetry values obtained using MatriXX for seven proton beams at four gantry angles
