Signal processing method, device and equipment based on interpolation algorithm

Abstract

This disclosure provides a signal processing method, apparatus, and device based on an interpolation algorithm, which can be applied to the field of medical imaging. The method includes: determining the m-th projection angle and the n-th projection angle from P projection angles; determining the m-th scattering signal and the n-th scattering signal corresponding to the m-th projection angle and the n-th projection angle, respectively; processing the m-th projection angle, the n-th projection angle, and the i-th interpolated angle between the m-th projection angle and the n-th projection angle using a sine function to obtain the m-th angle weight factor, the n-th angle weight factor, and the i-th interpolated angle weight factor; obtaining a distance weight factor based on a first interval angle number between the i-th interpolated angle and the m-th projection angle, and a second interval angle number between the i-th interpolated angle and the n-th projection angle; and processing the angle weight factor, the distance weight factor, and the scattering signal based on an interpolation algorithm to generate the i-th interpolated scattering signal corresponding to the i-th interpolated angle.
