Abstract

Provided is a novel aliasing elimination technique capable of suppressing noise amplification in an aliasing elimination calculation in parallel imaging and the like. The technique utilizes the fact that a phase of an image (a true image that is one of a plurality of images) to be separated from a main captured image obtained with the plurality of images superimposed is basically the same as a phase of an image obtained at a low resolution, to obtain a phase difference between a phase of a low-resolution image and a phase of the main captured image, and separates the true image by calculation using the phase difference and a pixel value of the main captured image. At this time, the low-resolution image is obtained by each of a plurality of receiving coils, and the true image is calculated after multiplying a plurality of low-resolution images by a complex number that minimizes the noise amplification.
