System and method for performing motion-insensitive resting three-dimensional magnetic resonance imaging

Abstract

The invention relates to a system and method for performing motion-insensitive resting three-dimensional magnetic resonance imaging. A method for generating a motion-corrected medical image includes obtaining, via a processor, k-spatial data of a region of interest acquired by a magnetic resonance imaging system using a 3D radial pulse sequence with ZTE acquisition, the pulse sequence including optional magnetization preparation pulses. The method also includes sampling, via the processor, the k-space data to obtain a plurality of interleaved k-space segments. The method also includes reconstructing, via the processor, one or more of the plurality of interleaved k-space segments to generate a respective motion navigator volume. The method even further includes co-registering, via a processor, each respective motion navigator volume to estimate motion, and performing motion correction on the one or more interleaved k-space segments and their corresponding k-space trajectories. The method also includes generating, via a processor, a motion-corrected volume from all the motion-corrected interleaved k-space segments and their corresponding motion-corrected k-space trajectories.

Description

technical field [0001] The subject matter disclosed herein relates to medical imaging, and more particularly to systems and methods for performing motion-insensitive resting three-dimensional magnetic resonance imaging. Background technique [0002] Non-invasive imaging techniques allow for obtaining images of internal structures or features of a patient / subject without performing invasive procedures on the patient / subject. Specifically, such noninvasive imaging techniques rely on various physical principles (such as differential transmission of X-rays through the target volume, reflection of acoustic waves within the volume, paramagnetism of different tissues and materials within the volume, target radionuclide in vivo decomposition, etc.) to acquire data and construct images or otherwise represent observed internal features of the patient / subject. [0003] However, imaging techniques such as magnetic resonance imaging (MRI) suffer from fundamental issues such as patient m...
