Abstract

This disclosure relates to a CT apparatus and an image processing method used by the CT apparatus. A method for automatically determining the best effective reconstruction gap is proposed, comprising: scanning a phantom to collect image data of the phantom; using a plurality of different gap values to reconstruct image of the phantom respectively, based on the image data, thus obtaining a plurality of images respectively associated with different gap values; selecting the best image from the plurality of images; and automatically determining the gap value associated with the best image, and save it as the best effective reconstruction gap. The best effective reconstruction gap may be used to remove band artifact when the image is reconstructed, so that image quality is improved and the CT apparatus can employ a low cost flat detector, further reducing the cost of the CT apparatus.
