Abstract
A computer-implemented method for determining spatially resolved radiation exposure information for a patient during an examination by an imaging X-ray device includes: determining preliminary dose information, when a compensating filter is used that is arranged between the patient and the X-ray tube unit in the X-ray field and causes an inhomogeneous dose distribution in the plane perpendicular to a central ray of the X-ray field; calculating dose distribution information using the preliminary dose information, which specifies at least the dose distribution of the X-ray dose acting on the patient in the portion of the X-ray field covered by the compensating filter, by a filter model that uses at least one filter parameter specifying the compensating filter and its arrangement in the X-ray field; and determining the patient entrance dose information using the dose distribution information.
