Claim 14:
15. A method for controlling a multi-slice computed tomography system comprising an X-ray source, a multi-row detector and an automated examination couch moving in a longitudinal direction, the method comprising:
acquiring a large volume computed tomography localizer radiograph of a subject to be imaged using the multi-slice computed tomography system;
defining an organ region in the large volume computed tomography localizer radiograph having the organ region substantially delimiting an organ of interest in the subject;
acquiring a large volume overview that comprises at least the organ region via a helical computed tomography scan of the subject having the subject being translated by the automated examination couch through an examination volume; and
increasing an X-ray cone angle of the computed tomography system in the longitudinal direction when the translation of the subject by the automated examination couch during the helical computed tomography scan causes the organ region to enter into the examination volume of the multi-slice computed tomography system and decreasing the X-ray cone angle in the longitudinal direction when the translation of the subject during the helical computed tomography scan causes the organ region to leave the examination volume.
