We are doing a project for which we have to find a use for a certain machine. This machine uses x-rays together with special software to make a 3D image of an object. The software can “cross-cut” the object so its inside can be seen as well. Lastly the software can analyze different aspects of the object, like density, size, etc. Therefore we are looking for samples to research with this machine that can also be useful for certain industries. These samples have a few prerequisites. -The sample cannot be larger than 2x2x2 centimetres -The sample’s state must be solid -The sample should preferably be made of either a porous or a light material -The sample shouldn’t consist of living animal tissue We would really appreciate it if you would share your ideas with us.
