Abstract: The application relates to a method and device for removing a scanning bed from a CT image. The method includes steps: reading a three-dimensional CT image, counting an amount of kernels in a CT apparatus and initializing sub-algorithms through a main thread of an image processing apparatus; extracting two-dimensional scanning images from the input three-dimensional CT image, automatically allocating the two-dimensional scanning images to kernels through the main thread of the image processing apparatus by sharing a memory, thereby realizing a multi-thread parallel processing to perform a bed removing operation on the two-dimensional scanning images; and ending the parallel processing and outputting a three-dimensional CT image without scanning bed information through the image processing apparatus. The method of the disclosure is very effective and accurate.
