Patent ID: 8384901

Claim:
A method of tomographic examination of objects, comprising: providing a source of transmittable electromagnetic radiation; scanning an object with a beam of electromagnetic radiation emanating from the source of transmittable electromagnetic radiation; providing a single radiation detector, wherein the detector is positioned at a distance from the source of electromagnetic radiation such that all of the transmitted electromagnetic radiation is received by the detector; discretely changing the object's angular position with reference to the electromagnetic radiation beam; registering the intensity of radiation passed through the object during scanning; and processing the obtained information to reconstruct the object's structure; wherein during scanning, formation of an electromagnetic radiation beam with discretely variable cross-sectional dimensions of the beam is performed; wherein the measure of each modification of one of the beam's cross-sectional dimensions corresponds to a required resolution characteristic; wherein registration of the radiation intensity is accomplished after each change of the cross-sectional dimension of the beam, and in the course of processing, a difference of two registered intensity values is found with obtaining a plurality of values to be applied for reconstruction of the object's structure.
