The embodiments relate to a method, an analyzer, a radiation dose disturbance system, and a computer program for automatically calculating a target radiation dose of ionizing radiation. In this case, both patient-specific parameters and equipment-specific parameters are taken into account. On a cloud-based data store, reference images are read out that concern the same anatomical target region in which the imminent examination is also intended to be carried out. The anatomical target region is advantageously determined in a manner dependent on the clinical issue. The reference images are evaluated with regard to radiation dose and image quality in order to generate a target radiation dose with a corresponding control command.
