Abstract

The invention provides a magnetic resonance image reconstruction method. Compared with a prior art, the magnetic resonance image reconstruction method selects same or different convolution kernels to perform multiple iterative computations on imaging signal data so as to effectively remove noise in the signal data, achieve a more obvious noise suppression effect, and obtain images with higher signal-to-noise ratios. The invention further provides a magnetic resonance image reconstruction apparatus.

Description

Technical field

[0001] The invention relates to the field of magnetic resonance imaging, in particular to a method and device for reconstructing a magnetic resonance image.

Background technique

[0002] At present, in the process of MRI multi-channel acquisition image reconstruction, methods such as SOS are generally used to simply merge the data acquired by each channel. The disadvantage of this method is that the weight of channels with low signal-to-noise ratio is not well suppressed in the merging process, which will affect the overall imaging quality. Therefore, it is necessary to further study the method of improving the image signal-to-noise ratio.

Content of invention

[0003] In order to solve the above-mentioned problems of inconspicuous image noise suppression and unsatisfactory quality of acquired images, the present invention provides a magnetic resonance image reconstruction method and device.
