Method and device for medical imaging for representing a 3D volume containing at least one introduced foreign object

A method of medical imaging for representing a 3D volume with at least one foreign object introduced into a tissue, which foreign object comprises at least one individual foreign object, wherein each individual foreign object comprises at least one individual foreign object component, the method comprising:

• providing a 3D volume containing voxels of the at least one foreign object and voxels of tissue surrounding the at least one foreign object;
• identifying the voxels of the at least one foreign object by application of a processing rule;
• segmenting the voxels of the at least one foreign object from the voxels of the tissue surrounding the at least one foreign object while maintaining the 3D volume;
• segmenting, in a second segmentation step, the at least one foreign object into its individual foreign objects;
• segmenting, in a third segmentation step, the individual foreign objects of the at least one foreign object into the individual foreign object components of the individual foreign objects;
• generating a synthetic volume from a residual volume and the volume of the at least one foreign object;
• and
• representing the synthetic volume on a display device,
• wherein at least one of the second segmentation step and the third segmentation step comprises segmenting two or more contiguous groups of voxels based on calculation of a structure tensor.
