<p>The invention relates to an imaging method for defining the structure of objects. Current methods and apparatuses are complicated and expensive, and cannot be applied to purposes where a large amount of images is needed in a rapid succession. In the method of the invention, the object (13) under inspection and at least one radiation source (11) and at least one detector (12) are moved in relation to each other, so that the object under inspection passes through the radiation transmitted by the radiation source, and at least one detector is used for measuring the changes in the intensities of radiation absorbed, at least partly, in the object under inspection, as a function of the motion of the said object. Thus, the structural points needed for imaging the structure are defined from at least two directions, and as the passage of radiation in the object at the moment of measurement is always known, the three-dimensional structure of the object is calcutated.</p> |
