Abstract

A method to optimally set a position of a form filter in an x-ray image recording apparatus is proposed. The x-ray image recording apparatus has an x-ray radiation source and an x-ray radiation detector. An x-ray image is firstly recorded in a first position of the form filter. A new position of the filter is then calculated and automatically set with the aid of the x-ray image. A new x-ray image is then recorded. With a minimal dose of a patient, the method enables low contrast images to be recorded for a minimal main dose of the patient, in particular in a sequence.
