The invention relates to a method and a system for removing a bed image of a CT (Computed Tomography) image and application, and the method sequentially comprises the following steps: obtaining a continuous CT image sequence of a patient, and constructing three-dimensional body data; carrying out projection analysis on the three-dimensional body data along the z-axis direction, and respectively calculating to obtain a maximum value projection image and a minimum value projection image; performing first threshold segmentation based on the minimum projection image to generate a first mask; performing second threshold segmentation based on the maximum projection image to generate a second mask; and based on the first mask and the second mask, generating an accurate bed area mask which does not contain human tissues. According to the method, the maximum projection (reflecting the upper limit of the tissue) and the minimum projection (reflecting the characteristics of the bed) are fused, so that the segmentation ambiguity of a single threshold value method in an overlapped CT value interval is overcome, and the accurate separation of the bed and the human tissue is realized.
