Abstract
The present disclosure provides a system and method for couch position calibration. The method may include obtaining one or more first images of a couch at one or more first locations in a first device, each of the one or more first images corresponding to one of the one or more first locations, wherein the couch includes a mark, and the mark intersects a first reference plane of the first device at a plurality of first points of the mark; determining, in each of the one or more first images, a first position of a representation of each of the plurality of first points; obtaining correlation information between the first position and actual position of each of the plurality of first points; and determining one or more calibration images based on the correlation information and the one or more first images.
