Method for determining correct value for reduction of artifact with computer tomography for exploratory partial area of test body, involves arranging test body at position between X-ray radiation source and detector

摘要

The method involves arranging a test body (120) at a position between an X-ray radiation source and a detector. A radiography image of the test body is formed on an upper surface of the detector in a perfect manner. The test body is moved at another position between the X-ray radiation source and the detector. Independent claims are also included for the following: (1) a method for executing a computer tomography for a partial area of a test body by using correct value; (2) an arrangement for determining correct value for a reduction of artifact with a computer tomography to an exploratory partial area of a test body; and (3) an arrangement for executing a computer tomography for a partial area of a test body by using correct value.
