This week’s image comes to us from researchers at Massachusetts Institute of Technology (MIT). Anirban Basu et al, have developed a portable x-ray source to image low-atomic number, or low-Z materials, such as biological tissues. In their recent paper published in JPhysD, they describe the characterisation of the source — a Pt-coated silicon field emission cathode — in order to achieve high contrast images of a human hand and a computer mouse, for example, with the ability to resolve features as small as ~160 µm.
