Abstract
An image processing apparatus is disclosed for generating a 3D data record from a plurality of 2D data records. The 3D data record represents an object at least partially in three dimensions, and the 2D data records respectively represent a result of a detection of the object by means of a projection through the object onto a detection plane in two dimensions. In at least one embodiment, the image processing apparatus is designed to generate the 3D data record, in particular by back projection or by filtered back projection from the 2D data records. In at least one embodiment, the image processing apparatus is designed to allocate a no object value to at least one area of the 3D data record that does not represent an object, and to allocate a changed object value to at least one area of the 3D data record in which an object location is represented by an object value.
