A method for use in the X-ray imaging of an item 10 comprises positioning an electrically conductive X-ray transmissive material mesh screen 12 over and around the item and using an X-ray based imaging system to produce an image of the item, the mesh material screen 12 being located between the item and the X-ray based imaging system, transmitter 26 and receiver 28. The mesh screen 12 may comprise a woven fabric cover 16 such as a blanket with conductive strands and may be put over a frame 14 to form an enclosed space 18. Opaque markers 24 may be included on the mesh to provide a position reference for regions of interest 10a on the item. The mesh screen acts to reduce interference in the image by filtering out unwanted scatter and stray reflections and may produce a sharper x-ray image. |
