Title:
MAGNETIC RESONANCE IMAGING DEVICE AND IMAGE PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2021069886
Kind Code:
A
Abstract:
To acquire an image from which an FID artifact is removed even when parallel imaging is applied to imaging using a spin echo based pulse sequence.SOLUTION: An image processing unit of an MRI device includes an image re-construction section (PI arithmetic operation section), an artifact removing section, and a transformation section which performs transformation between measurement data (k space data) and image data, that is Fourier transformation and reverse Fourier transformation or the like. The artifact removing section calculates a phase of an original image signal of an analyte, that is an image signal from which the artifact is removed from an image re-constructed by using an echo signal, calculates a phase of the artifact area, and acquires an image signal from which the artifact is removed by using the phase of the image signal and the phase of the artifact on the basis of the relation between the phase and the signal value.SELECTED DRAWING: Figure 1
