Computer-implemented method for determining spatially resolved radiation exposure information, x-ray device, computer program, and electronically readable data storage medium

An X-ray device comprising:

• an X-ray tube unit having an optionally usable compensating filter, which brings about an inhomogeneous dose distribution in a plane perpendicular to a central ray of an X-ray field emitted by the X-ray tube unit;
• an X-ray detector;
• and
• a control device configured to:
• determine preliminary dose information that specifies a homogeneously distributed X-ray dose acting on a patient in an absence of the compensating filter;
• calculate dose distribution information using the preliminary dose information, wherein the dose distribution information specifies at least a dose distribution of an X-ray dose acting on the patient in a portion of the X-ray field covered by the compensating filter, and wherein the dose distribution information is calculated by a filter model that uses at least one filter parameter specifying the compensating filter and an arrangement of the compensating filter in the X-ray field;
• and
• determine patient entrance dose information that specifies the X-ray dose acting on the patient using the dose distribution information.

A non-transitory electronically readable data storage medium comprising a computer program, which, when the computer program is executed on a computing device, causes the computing device to:

• determine preliminary dose information that specifies a homogeneously distributed X-ray dose acting on a patient in an absence of a compensating filter arranged between the patient and an X-ray tube unit in an X-ray field that is configured to cause an inhomogeneous dose distribution in a plane perpendicular to a central ray of the X-ray field;
• calculate dose distribution information using the preliminary dose information, wherein the dose distribution information specifies at least a dose distribution of an X-ray dose acting on the patient in a portion of the X-ray field covered by the compensating filter, and wherein the dose distribution information is calculated by a filter model that uses at least one filter parameter specifying the compensating filter and an arrangement of the compensating filter in the X-ray field;
• and
• determine patient entrance dose information that specifies the X-ray dose acting on the patient using the dose distribution information.
