Estimating a radiation load quantity for an imaging system having a radiation source

A data processing apparatus comprising:

• at least one computing unit configured to:
• obtain a base model for determining a radiation load quantity depending on a set of input variables that comprise at least one radiation-source operating parameter;
• obtain measurement data measured for an imaging system, wherein the measurement data comprises the radiation load quantity for a multiplicity of different values of the at least one radiation-source operating parameter;
• generate a refined model by adapting the base model depending on the measurement data;
• define actual values of the set of input variables for the imaging system;
• and
• determine, using the refined model, an estimated value of the radiation load quantity depending on the actual values of the set of input variables.
