Design outcomes

Primary

Measure	Time frame
The aim of the present study is to verify to what extent the use of surface scanning by the CE certified Catalyst ™ system provides equally precise storage control parameters as generated by reference methods. With an optimum storage precision, the frequency of the storage control could be reduced by means of additional ionizing radiation.	—

Secondary

Measure	Time frame
Furthermore, the extent to which movements of the patients take place during dose application should be registered.	—
