Described is a method for the visualization of medical image data as volume data. As part of the method, medical image data is acquired. A 3D mask is produced by segmenting the image data and classifying the segmented regions into predefined classes. Furthermore, the image data and the mask data are saved in two separate 3D texture files. A translation vector is then calculated, which describes the displacement of a segmented volume element between an original position and a destination position. In addition, a pictorial display of the image data is produced by applying a raycasting method to the stored image data. Finally, a displacement by the translation vector of a segmented volume element in the pictorial display is performed. A visualization entity is also described. Moreover, a medical imaging system is described.
