In a method for imaging in digital dental radioscopy making use of a sensor array, the individual image elements of which are smaller than a desired local resolution so that a plurality of image elements forms a respective effective image element, first reference signals, which are generated by the image elements of the sensor array when said sensor array is not exposed to X-radiation, are initially detected. In addition, second reference signals, which are generated by the image elements of the sensor array when said sensor array is exposed to X-radiation, are detected. Subsequently, defective image elements are determined on the basis of the detected first and second reference signals, whereupon an image of an object is produced using exclusively the image elements that have been determined as being non-defective. Furthermore, during production of the image of an object, it can be determined for the object signals detected for the respective image elements whether said image elements have been hit directly by an X-ray quantum. Image elements that have been hit directly by an X-ray quantum are not used for producing the image of the object.
