Abstract
The non-destructive testing of materials such as for disease in living trees is carried out by determining at each of a plurality of positions in a given cross-section of said material to be tested the coefficient of absorption of a predetermined radiation source, and converting said coefficient of absorption at each of said position into a computerized tomographic display. The radiation source is selected from the group consisting of gamma, x-ray, and neutron radiation.
Claims22
A method for the non-destructive testing of immobile objects such as for disease in living trees, or the like comprising the steps of mounting on one side of said object a portable source of radiation and on the opposite side of said obejct a portable detector for such radiation, indexing said source and said detector cooperatively about said object through a plurality of positions in a given cross-sectional plane, passing a beam of predetermined radiation through said object and detecting the beam at each of said positions, determining responsive to said detection the coefficient of absorption of radiation of said object, and converting said coefficient of absorption at each of said positions into a computerized tomographic display.
Apparatus for the non-destructive testing of immobile objects such as for disease in living trees comprising a supporting frame adapted to be removably mounted on said object to be tested, a source of radiation and a detector for said radiation mounted to pass a beam of said radiation through said object, means responsive to said detector for measuring the coefficient of absorption of said source by said object and computer means for displaying tomographically said coefficient of absorption.
