Provided in embodiments of the present invention are a magnetic resonance image processing method and device, and a computer-readable storage medium. The method includes: determining a central angle; converting, on the basis of the central angle, a radio-frequency field pattern of a radio-frequency transmitting coil into an angular pattern; acquiring, on the basis of a trigonometric function value of the angular pattern, a radio-frequency transmitting field pattern of the radio-frequency transmitting coil; and correcting, on the basis of the radio-frequency transmitting field pattern, a magnetic resonance image to be corrected.

Magnetic resonance image processing method and device, and computer readable storage medium

Embodiments of the present invention provide a magnetic resonance imaging system and a method for obtaining magnetic resonance imaging data. The method comprises: applying a fat suppression pulse before the start of any repetition time of an imaging sequence; performing a plurality of echoes in the repetition time, wherein first image data when water and fat are in phase and second image data when water and fat are out of phase are obtained during each echo of the plurality of echoes; and obtaining fat-suppressed image data according to the first image data and the second image data.

Method for obtaining magnetic resonance imaging data and magnetic resonance imaging system

Systems and methods for suppressing background in time-of-flight (TOF) magnetic resonance angiography (MRA) are disclosed. An exemplary method includes obtaining a first TOF image through a high-resolution acquisition with a saturation band on one side of an imaging slab, obtaining a second TOF image through a low-resolution acquisition with two saturation bands on both sides of the imaging slab, and subtracting the second TOF image from the first TOF image to obtaining a subtraction TOF image. Post processing such as maximum intensity projection (MIP) is performed on the subtraction TOF image.

Systems and methods for background suppression in time-of-flight magnetic resonance angiography

The present invention provides a method and apparatus for correcting a uniformity of a magnetic resonance image, the method including: acquiring a first uniformity enhancement image by a phased-array uniformity enhancement method; and dividing the first uniformity enhancement image by a receiving sensitivity distribution value of a body coil in a magnetic resonance imaging device, so as to acquire a second uniformity enhancement image. The method further includes: dividing the second uniformity enhancement image by a spatial signal distribution value resulting from a field strength distribution of a transmitting radio-frequency field, so as to acquire a third uniformity enhancement image.
