Abstract: The invention relates to a method to measure the entrance dose of a radiology apparatus of the type comprising an X-ray beam source, and a detector for the X-ray beam after it has passed an object of interest carried on a table placed between the source and the detector, wherein the X-ray beam source is placed above said table and wherein the distance between the X-ray beam source and the object is estimated taking into account the object's morphology, for determining said entrance dose. An attenuation-ratio is calculated depending on energy-levels of the X-ray beam leaving the X-ray beam source and arriving at the detector respectively, and that the object's thickness is calculated depending on said attenuation-ratio, said thickness together with the table-position defining said distance between the X-ray beam source and the object.
