1. A method for detecting damage to silicone implants in an object region of a human body using a computed tomography device, the method comprising:

  • a) taking at least two computed tomography recordings of the object region, each at different X-ray spectra or different mono-energies of the X-ray radiation;

    b) reconstructing the at least two computed tomography recordings to form 3D data sets which contain X-ray attenuation values or equivalent material densities in terms of a basic material decomposition of voxels of the object region;

    c) determining a data point in a diagram for each voxel of interest, the X-ray attenuation values for different X-ray energies being plotted against one another;

    d) comparing the data point, or of another value for each voxel of interest determined from the X-ray attenuation values, with known data points or values of at least one of body tissue and silicone; and

    e) outputting a note or warning if at least one ofthe data point or other value deviates from the known data points or values for body tissue by at least a first threshold value, andin the event of simultaneous approximation to the known data point or value for silicone by less than a second threshold value.
