Abstract: Provided is a technology capable of effectively obtaining a ringing correction effect even for a two-dimensional image or a three-dimensional image with a simple CNN configuration. A CNN that has been trained to perform ringing correction for a direction of a dimension lower than a dimension of an image that is a correction target is prepared, and the CNN is applied in multiple stages to perform the ringing correction. For training the CNN, an image captured by increasing a measurement matrix size in one or two directions need only be used, thereby reducing an imaging time for acquiring training data and a burden of data processing, and enabling handling of images of various dimensions.

An inverse Fourier transform is performed on the k-space data to obtain a final image.
