Patent ID: 7502437

Claim:
Coherent scatter computer tomography apparatus for examination of an object of interest, comprising: a source of radiation; a first radiation detector; and a second radiation detector; wherein the source of radiation generates a radiation beam adapted to penetrate the object of interest in a fan plane and wherein the source of radiation is inclined with respect to the fan plane; wherein the coherent scatter computer tomography apparatus further comprises a collimator arranged between the source of radiation and the object of interest, wherein the collimator comprises a plurality of collimator portions that collimate the radiation beam in a direction substantially perpendicular to the fan plane, wherein the first radiation detector is arranged opposite to the source of radiation in the fane plane; wherein the first radiation detector is arranged to detect a first radiation of the collimated radiation beam; wherein the second radiation detector is arranged opposite to the source of radiation with an offset from the fan plane in a direction normal to the fan plane; wherein the second radiation detector is arranged to detect a second radiation of the collimated radiation beam scattered from a location in the object of interest; wherein at the location, the second radiation has a dimension in the direction normal to the fan plane; wherein a scatter angle between photons of the second radiation scattered at the location along the dimension from the fan plane is constant.
