title: Mach bands and density perception.
abstract: Perception of a roentgen image is greatly influenced by the production of Mach bands by the retinal neural networks. The mechanism of their production and contributing factors such as lateral inhibition, projection, contour, film density, object density, and background are discussed. Although Mach bands often facilitate perception of roentgen density, misinterpretation of their significance may lead to errors in diagnosis.
