Method for tomographic image reconstruction of an object that comprises two asynchronously rotating components, whereby sufficient projections are recorded at relative rotation angles and then converted to absolute angular values

摘要

Method has the following steps: tomographic projections are recorded at individual angular positions of the object components, for both object components and the relative rotation angle determined; for one or more selected values of the relative angle, the absolute rotational angle of an object component relative to the tomograph is measured and simultaneously used for measuring the absolute angle of a tomographic projection. Sufficient projections are recorded between 0 and 360degrees for image reconstruction.
