In a method, a personal dose report image is received via a first interface. The personal dose report image includes personal data and dose data of an imaging by way of ionizing radiation. The personal data and the dose data are contained as rasterized text in the personal dose report image and the personal data or the dose data includes a first signal word. A first position of the first signal word in the personal dose report image is determined through optical character recognition. An image area in the personal dose report image is determined based on the first position, the image area including at least a part of the personal data. An anonymized dose report image based on the personal dose report image is determined, at least the image area of the anonymized dose report image corresponding to the image area of the personal dose report image being anonymized.
