<p>The present invention provides a radiotherapy treatment table top device ( 1) with high rigidity and load carrying capability, while at the same time providing a low attenuation of radiation. The table top device comprises a core (2), preferably made of a foamed material, at least partly enclosed by a skin (3,3') that preferably is made of a fiber material, whereby the core (2) is sandwiched between the skin (3,3') on opposite sides (6,7) of the table top device ( 1). The core (2) is non-homogenous with respect to density. Preferably the core has a varying density, with higher density close to at least one interface (8, 8') with the skin (3), such as a higher density in an upper layer (4) and a lower layer (5) close to the skin (3,3') and lower density towards the central plane of the core (2).</p> |
