MELO C, Pedro  y  ESCAFFI J, J. Antonio. MACH BANDS IN RADIOLOGY. Rev. chil. radiol. [online]. 2010, vol.16, n.2, pp. 86-89. ISSN 0717-9308.  http://dx.doi.org/10.4067/S0717-93082010000200009.

Mach bands represent optical psychophy-siological edge-enhancement phenomena perceived in different forms by different observers; they originate in adjacent areas of diverse density, giving rise to a thin black strip (negative Mach band) or a white strip (positive Mach band). They can be identifed in simple radiographic examinations, including chest radiography, and also in CT topograms. Proper recognition of Mach bands helps to correctly interpret radiological examinations.

Palabras llave : Computed tomography; Mach bands; Radiography.
