DEVICE FOR THE ACCURATE ANATOMICAL LOCATING OF TOMODENSITOMETRIC SECTIONS

Means for locating accurately without ambiguity tomodensitometric sections sloping in any way with respect to an original predetermined plane. At least one locating element is disposed on the part to be examined by conventional tomodensitometry, this element having a baseline situated in the original plane and having at least one characteristic such as density, varying continuously or substantially continuously along a direction perpendicular to this baseline, the variation of this characteristic being measurable on the tomodensitometric images of the different sections; this characteristic may be in particular a dimension of the element: width perpendicular to the direction perpendicular to the base in the case where the element is a triangle.
