Medical image quality enhancement

 

 

Dual-energy computer tomography

The research is supported by the Economic Developmental Operative Program with the cooperation of General Electric and the University of Szeged.

Introduction:

The electrons, accelerated by corresponding electric field, can produce such high energy photons, that pass through organic and inorganic materials. The spectrum of the generated X-ray radiation characterizes the material of the anode.

 

 

The extent of the absorption depends on the photon energy and the compound of the absorbing material, hence the absorbed X-ray photons depict shadow image on the detector. Materials with similar absorption give similar shadow  image, so they can be hardly distinguished. But the modern dual-energy equipments can differnetiate materials with an additional projection (using different energy). Materail specific images (bone image, soft tissue image) can be obtained from dual energy exposures. Such equiment is the dual energy CT.
