Abstract

A method is disclosed for determining bone mineral density values of an object. In an embodiment, the method includes acquisition of first two-dimensional projection overview image data of the object to be examined in an image detail with a first X-ray energy; acquisition of at least second two-dimensional projection overview image data of the object to be examined in an image detail with at least one different second X-ray energy; determining a bone overview image data record using the first and second projection overview image data; determining at least one specific evaluation region of the image detail using the bone overview image data record; and determining a bone mineral density value for the specific evaluation region of the image detail using the image data of the bone overview image data record in the specific evaluation region. A computerized tomography system for implementing a method is also disclosed.
