Abstract:
Methods and devices for reconstructing dual-energy CT images are provided. In one aspect, CT scan is performed with a high energy and a low energy periodical and alternatively changed on a scanning target, reconstruction data for a high-energy image of a current reconstruction position is obtained based on whether a circle of high-energy scan closest to the current reconstruction position of the scanning target is a full circle of scan, the high-energy image of the current reconstruction position is reconstructed according to the reconstruction data of the high-energy image; reconstruction data for a low-energy image of the current reconstruction position is obtained based on whether a circle of high-energy scan closest to the current reconstruction position of the scanning target is the full circle of scan, the low-energy image of the current reconstruction position is reconstructed according to the reconstruction data of the low-energy image.

Claim (Index 4):
The method of  claim 3 , further comprising:\n when the low-energy scan is not performed on the current reconstruction position,\n calculating a first distance between the current reconstruction position and a finishing position of a previous circle of low-energy scan adjacent to the circle of high-energy scan passing through the reconstruction position and a second distance between the current reconstruction position and a starting position of a next circle of the low-energy scan adjacent to the circle of high-energy scan passing through the current reconstruction position, respectively; and \n determining the circle of low-energy scan corresponding to a smaller one of the first distance and the second distance to be the circle of the low-energy scan closest to the current reconstruction position.
