Description

Digital subtraction radiography serves angiography [1] and other medical applications successfully to extract minute x-ray signals from noisy backgrounds. Verhoeven [2] demonstrated that detecting surprisingly small changes in x-ray absorption makes this technique useful for industrial applications as well. I detect very small areal density differences and also wires as small as 2 µm in diameter although the spatial resolution of my x-ray apparatus is 1 mm.
