COMPUTED TOMOGRAPHY SCANNER Russian patent published in 2015 - IPC A61B6/03 G01N23/04 

FIELD: physics.

SUBSTANCE: computed tomography (CT) apparatus comprises a scanning tunnel, a fixed X-ray source placed around the scanning tunnel and having a plurality of focal spots which emit radiation and a plurality of fixed detector modules placed around the scanning tunnel opposite the X-ray source. One part of the modules from the plurality of detector modules is located in a first direction and the second part of the modules from the plurality of detector modules is located in a second direction, and the arrangement of said parts of the detector modules is L-shaped. The first direction forms a straight line by connecting the centre points of the radiation beam receiving surfaces of one part of the detector modules. The second direction forms a second straight line by connecting centre points of the radiation beam receiving surfaces of the other part of the detector modules, which cross at a certain point when viewed in a plane which crosses the scanning tunnel. The radiation beam receiving surfaces of one part of the detector modules are inclined relative to the first direction and face the X-ray source, and the radiation beam receiving surfaces of the other part of the detector modules are inclined relative to the second direction and face the X-ray source.

EFFECT: fixed CT apparatus without a gantry according to the invention has small dimensions and high data identification accuracy.
