APPARATUS FOR FORMING DUAL ENERGY RADIOGRAPHIC IMAGE DATA Russian patent published in 2021 - IPC A61B6/03 

FIELD: medicine.

SUBSTANCE: radiation detector of the apparatus for forming dual-energy radiographic image data is placed relative to the radiation source so that at least part of the area between the radiation source and the radiation detector constitutes a study area for placement of the object. A raster filter is placed between the study area and the radiation source. A focal point is created on the target using the radiation source in order to produce radiation. The focal spot is moved over the target surface in a first direction using the radiation source. The raster filter contains a structure with a first orientation so that movement of the focal point in the first direction results in a corresponding change in the intensity of the radiation transmitted through the raster filter. The focal spot is moved over the target surface in a second direction orthogonal to the first direction using the radiation source. The raster filter contains a structure with a second orientation orthogonal to the first orientation so that movement of the focal point in the second direction results in a corresponding change in the energy spectrum of the radiation transmitted through the raster filter. At least part of the radiation transmitted through the raster filter is detected by means of the radiation detector.

EFFECT: application of the described group of inventions allows to expand the eange of technical means.
