Automatic bone density and structure determination, for orthodontic application, by use of reference object for determination of gradients and texture by comparison with test structure

摘要

Measurement system comprises an X-ray source (1) for imaging an object (3). An additional reference body (4) is placed next to the object (3) so that the parameters of the reference body can be used to determine more quantitatively the density and or structure of the bone object being imaged.
