1. A method for visualization of plaque deposits from 3D image data records of vessel structures in which at least one section of the vessel structure with the plaque deposits is segmented in the 3D image data record in order to obtain segmented image data, the method comprising: producing a synthetic 3D model image of the at least one section of the vessel structure and of the plaque deposits from the segmented image data, the synthetic 3D model image including only boundary surfaces of the vessel structure and of the plaque deposits, the synthetic 3D model image being produced by three-dimensional interpolation between pixels associated with boundary surfaces of the vessel structure, and between pixels associated with boundary surfaces of the plaque deposits in order to obtain a uniform grid at pixels for the 3D model image, wherein at least a partial image of the synthetic 3D model image is visualized.
