The invention discloses a method, device, equipment and storage medium for identifying an effective scanning range of a CT scanning bed, wherein the method comprises: in different scanning modes, simulating running a scanning bed with different groups of scanning parameters, and each group of scanning A scanning bed image is formed under the parameters; a plurality of scanning bed images formed under multiple sets of simulation parameters are obtained; the imaging data of each scanning bed image is determined according to all scanning bed images, each scanning bed image corresponds to a group of imaging data, and each The image data includes the bed start point, bed end point and scan length; compare multiple sets of imaging data to determine a group of imaging data with the smallest scan length in each group of imaging data. CT scan bed for location marking. According to the method for identifying the effective scanning range of the CT scanning bed of the present invention, the effective scanning range of the scanning can be marked, which is beneficial to improve the scanning efficiency, make full use of medical resources, and at the same time, avoid the problem of multiple scanning radiation for patients.
