1. A computer tomography apparatus for examination of an object of interest, the computer tomography apparatus comprising:

  • a source of radiation;

    a scatter radiation detector for receiving a scatter radiation scattered by the object of interest, said detector being arranged opposite to the source of radiation with an offset with respect to a fan plane which extends through the object of interest and the source of radiation; and

    a first collimator comprised of;

    a second collimator focused at the source of radiation; and

    a third collimator focused at the section of the object of interest;

    wherein the scatter radiation detector has a plurality of detector regions organized substantially as a detector matrix comprised of matrix elements defined by horizontal and vertical detector lines, each of the plurality of detector regions having at least one energy resolving detector element;

    wherein the first collimator is adapted such that radiation impinging on the at least one energy resolving detector element of a respective region of the plurality of regions is substantially restricted to scatter radiation scattered from a predetermined section of the object of interest, the dimensions of which correspond substantially to a matrix element of said detector matrix;

    wherein the source of radiation is adapted such that a fan beam of radiation is applied to the object of interest in the fan plane.
