A method and a tomography unit are disclosed for carrying out an analysis of a movement of an object on the basis of at least two images produced with the aid of a tomography unit at consecutive instants. A) vector field, formed from displacement vectors, is determined from in each case two images and at least one divergence value is calculated for analyzing the movement from the vector field. The divergence value renders it possible in a simple way to acquire a contraction movement or expansion movement in a qualitative and quantitative fashion, the sign of the divergence value specifying the type of movement, and the absolute value specifying the magnitude of movement of the object.
