Method to correct imaging errors of an x-ray image intensifier system and associated x-ray image intensifier system

A method for correcting imaging errors in an x-ray intensifier system comprising an image converter tube that converts incoming x-ray radiation into visible light, and a digital camera system that is optically downstream of said image converter tube, said digital camera system comprising an image sensor that converts said visible light into a digital image, and comprising an electronic image processor that processes said digital image, said method comprising the steps of:

• with a magnetic field probe, detecting a characteristic of a magnetic field that is present in an environment in which said image converter tube is located, and emitting a probe output signal from said magnetic field probe that represents said characteristic;
• supplying said probe output signal to an imaging error processor and, in said imaging error processor, analyzing said characteristic and automatically quantifying an imaging error resulting from said magnetic field;
• in said imaging error processor, automatically determining at least one parameter of a correction map, dependent on the quantified imaging error, that corrects the quantified imaging error;
• and
• supplying said correction map to said image processor and, in said image processor, correcting said digital image using said correction map.
