Alessandro Vallebona

from Wikipedia, the free encyclopedia
Axial transverse X-ray stratigraphy of the midface: the gray veil is created by the blurred planes that are in front of and behind the sharply displayed plane and therefore appear as a blurred structure.

Alessandro Vallebona (born March 2, 1899 in Genoa ; † December 1, 1987 ibid) was a radiologist in Genoa.

In 1930 he developed the basics of tomography , which he himself called axial transverse X-ray stratigraphy . To do this, Vallebona ran an X-ray source and a film around a patient in opposite directions, so that only the plane at the pivot point was shown in focus. The other levels in front of and behind the sharply depicted level appeared on the X-ray image as blurred structures due to their motion blur. Modern tomographs use a computer to extract those smear structures from the X-ray image. In 1970 A. Vallebona was awarded the X-ray plaque .
