Pointwise scans of dose profiles were also performed during commissioning but this takes a lot of time because for each measured point, the DMLC field has to be treated once. So this is by no means suitable for a routine measurement. But this gives the highest precision if a small probe is used and we also wanted to try out the new Diode from PTW. Here the measured and calculated dose profiles are projected on the fluence of the investigated leaf pair. The dose peaks are still somewhat more pronounced in the measurement compared to the CadPlan dose profile, but the agreement is generally, I would say, very good.
