Method for actuating a medical imaging device

A training method for providing a trained function, comprising:

• provisioning, via a training interface, a training respiratory curve of a training patient and a comparison measurement parameter linked to the training respiratory curve of the training patient, the comparison measurement parameter determining a temporal resolution of a training slice image data set comprised by a training image data set of a measurement region affected by respiratory movement of the training patient for at least one z position comprised by the measurement region, the training slice image data set being generated, via a training imaging device, upon application of the comparison measurement parameter, and the training slice image data set being based on a plurality of training projection data sets from various projection angles with relative rotational movement between a radiation source of the training imaging device and the training patient;
• applying, via a training computing device, the trained function to the training respiratory curve to derive a training measurement parameter;
• adapting at least one parameter of the trained function, via the training computing device, based upon a comparison of the training measurement parameter derived and a corresponding comparison measurement parameter;
• and
• providing the trained function via a second training interface.
