Embodiment Construction

[0059] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0060] like figure 1 As shown, the magnetic resonance imaging system may include a scanning imaging device 110 and an input / output device 120 . When performing scanning imaging, the subject can move to the scanning field of view along with the scanning table. A subject may be, for example, a human or other animal body. For example, the subject may be a human body. The scan area may include a portion of the body. For example, the scan area may include tissue of the patient. Tissues may include, for example, lung, prostate, breast, colon, rectum, bladder, ovary, skin, l...

Abstract

The invention relates to a magnetic resonance imaging method and device, computer equipment and a storage medium. The magnetic resonance imaging method comprises the steps: a magnetic resonance signalof a detecting object is obtained, and a K space is filled with the magnetic resonance signal and comprises a full sampling area and an undersampling area; a filter is generated according to the fullsampling area; full sampling area data are subjected to one-time and continuous multi-time convolution operation based on the filter to obtain the coefficient related to the filter, and the obtainedcoefficient is substituted into the filter; a K space dataset is rebuilt based on the filter with the coefficient, and the corresponding undersampling area in the rebuilt K space dataset is filled; and the rebuilt K space dataset is subjected to Fourier transformation, and a complete magnetic resonance image of the detecting object is obtained. By adopting the magnetic resonance imaging method, artifacts can be effectively restrained, and the better imaging quality and the higher imaging speed are provided.

Description

technical field [0001] The present application relates to the technical field of magnetic resonance imaging for medical diagnosis, in particular to a magnetic resonance imaging method, device, computer equipment and storage medium. Background technique [0002] Magnetic Resonance Imaging (MRI) technology has the characteristics of non-invasiveness, no ionization, and no radiation. The images obtained by it are clear, fine, high-resolution, and good in contrast. Greatly improve the diagnostic efficiency. As the front end of the receiving chain, the radio frequency (Radio Frequency, RF) receiving coil plays a very important role in the image quality and directly affects the signal-to-noise ratio of the image. [0003] Fast magnetic resonance imaging methods can be roughly divided into three categories: fast scanning imaging, parallel imaging, and K-space sparse sampling imaging. Among them, parallel imaging has been widely used in clinical magnetic resonance imaging. The pa...
