According to Prof. Dr. J. W. Rohen. The model shows the anatomical structures of 10 consecutive horizontal sections through the human head oriented to the plane usual in CT and MR imaging (CA-CP plane) and which have the same section thickness (0.8 cm). The sections were modelled on original preparations and are illustrated from above. Each cross section pivots and can be removed from the stand. Natural size in special plastic. With explanatory booklet on the green base.
