| Abstract: In this study different methods of medical
imaging are considered along with the possibility of
combining information offered by them. One of the
techniques of special interest is positron emission
tomography (PET). This medical imaging technique gives
information about metabolic processes in the human body.
One of the main defiance of this method is attenuation of
gamma photon in interaction with tissues and organs inside
the body. This phenomenon can be fixed by the attenuation
correction factor. The factor can be obtained using
Computerized tomography (CT) imaging with aim to map
PET image with linear attenuation coefficient. The PET and
CT images are matched using image registration technique
which provides determination of attenuation coefficient
space distribution. Using the attenuation coefficient the
pixels intensity of PET image can be scaled by the reciprocal
value of attenuation coefficient with propose of attenuation
correction. |
