Abstract

So thickness of the sectioned layer on the chest-tomography is influenced by the various factors, it can't be always constant, and generally it depends especially on the amplitude of the tube. Then we tried the fundamental experiment using the thin wires under the general conditions, compared the findings of the sectioned lung-preparation with the tomographical one, and besides perfoamed the clinical examination by the simultaneous tomography, for the purpose of investigating the Correlation between the amplitude of the tube and thickness of the sectioned layers. Thus we could obtain adequate thickoess of the sectioned layers at each angle form 20°to 70°.
