In a method for operation of an imaging medical apparatus, a recumbent
board supporting an examination subject is positioned in the scan region
of the medical-technical apparatus, an exposure of both a section of the
recumbent board and of a part of the tissue of the examination subject to
be examined in the scan region is generated, the acquired real position
of the section of the recumbent board is compared with an expected
position of the recumbent board by image evaluation of the exposure
generated with the medical-technical apparatus, and the exposure
generated with the medical-technical apparatus of the examined tissue is
corrected using the expected-real comparison of the position of the
recumbent board.
