1. A method for generating an image of an examination subject using a tomography-capable X-ray device having a multi-row X-ray detector array, an X-ray radiator rotatable around a system axis that emits a conical X-ray beam, and a positioning device adapted to receive an examination subject thereon for positioning the subject in a direction parallel to said system axis at different positions parallel to the system axis relative to the X-ray radiator, comprising the steps of: generating raw data by the radiating said examination subject with said X-ray beam in a rotation scan to acquire a plurality of projections during at least one revolution or partial revolution of said X-ray radiator around the subject, and by a linear scan wherein transmission values are acquired at different positions of said subject parallel to said system axis, without rotation of said X-ray radiator, with all of said transmission values generated by said linear scan being acquired in a continuous linear scanning movement; and generating an image of said subject from said raw data generated by said rotation scan and said linear scan.
