The present invention provides a radiation device that includes a device for retaining therein the body part in a uniform position. In addition, at least two reference materials that have attenuation characteristics are used and retained in the retaining device. The reference materials are being positioned for the comparative determination during a simultaneous irradiation of the body part and the reference materials. The attenuation characteristics of the reference materials are selected in correspondence to the attenuation characteristics of the body materials in the body part. A radiation device for simultaneously irradiating the body part and the reference materials is used to create attenuated beams. A detector is used to detect the attenuated beams as attenuated values. A calculating device is included for calculating the proportion of the body materials that define a particular body part of interest based on the attenuated values of the materials and the body part.
A radiation device for comparatively determining a proportion of body materials defining a body part, said radiation device comprising:
A method for comparatively determining a proportion of body materials defining a body part, comprising the steps of:
