Cone beam computed tomography imaging method and system based on scattering recognition

The invention discloses a cone-beam computed tomography imaging method based on scattering recognition, which relates to the technical field of image processing and comprises the following steps: controlling an emitter to emit transmission rays with a preset spectral width to a target tissue; acquiring the first ray intensity of the transmission ray at each pixel point after penetrating through the target tissue through a top detector; acquiring second ray intensity of the transmission ray at each pixel point after scattering attenuation of the collimator through a base layer detector; according to the first ray intensity and the second ray intensity at the corresponding pixel points, estimating the scattered ray intensity after the transmission ray penetrates through the target tissue; on the basis of the estimated scattered ray intensity, estimating primary ray intensity after the scattered rays are removed through the second ray intensity; and constructing tomography imaging of the target tissue according
