Abstract: The present disclosure relates to a method for removing an artifact in an image, an electronic device, and a storage medium. The method includes obtaining original scan data of a target object collected by a detector during a first imaging scanning, and performing an artifact correction on the original scan data with a scattering reference signal. The original scan data includes a scattering signal. The scattering reference signal is obtained based on energy data of the detector obtained under a condition that no slit is applied and energy data of the detector obtained under a condition that a slit is applied during a second imaging scanning.

Abstract: The present invention provides an economical and efficient means for removing grease and other contaminants from restaurant wastewater. There is a need for an easily removable drain filter. The present invention meets this need, as it is a low-cost, disposable, and efficient means for removing these contaminants.
