Abstract

A tomographic device includes a recording unit with a central system axis, a patient couch movable along the system axis and also a radiation source and a radiation detector interacting with the radiation source. The inventors have recognized that a rapid, precise and reliable positioning of a first recording area can be achieved by the positioning being based on a trained model, wherein the model has been trained with training positions. The tomographic device therefore includes a computing unit, which is designed for calibration of a first position of the first recording area relative to the recording unit based on the trained model. Furthermore the tomographic device includes a control unit for positioning the first recording area in the first position by moving the patient couch relative to the recording unit. The tomographic device is designed for a first tomographic recording of the first recording area in the first position.
