Problems solved by technology

[0003] Based on different clinical applications, the magnetic resonance imaging system can be configured to perform imaging scans on human tissues according to different scan sequences. Generally, different scan sequences have their own characteristics in clinical applications, such as advantages and disadvantages. For example, for For some scanning sequences that can achieve fast data acquisition, it can achieve fast imaging and is widely used in clinical practice, but there are also image quality problems, such as blurred images that are not conducive to medical observation

Embodiment Construction

[0059] figure 1 A schematic structural diagram of a magnetic resonance imaging (MRI) system is shown, and the magnetic resonance imaging system 100 includes a scanner 110 . The scanner 110 is used for magnetic resonance scanning of an object (such as a human body) 16 to generate image data of a region of interest of the object 16 , and the region of interest may be a predetermined imaging site or imaging tissue. In an embodiment, the image data may include two-dimensional image data of multiple slices (or slices) of the region of interest.

[0060] The magnetic resonance imaging system may include a controller 120 coupled to the scanner 110 for controlling the scanner 110 to perform the above-mentioned magnetic resonance scanning procedure. Specifically, the controller 120 can send a sequence control signal to relevant components of the scanner 110 (such as a radio frequency generator, a gradient coil driver, etc. to be described below) through a sequence generator (not shown i...

Abstract

The embodiment of the invention provides a method for collecting and processing magnetic resonance data, a magnetic resonance imaging system and method and a computer readable storage medium. The method for collecting and processing magnetic resonance data comprises: filling K spaces with multiple sets of echo data collected after imaging tissue is excited multiple times, and the filling sequences of at least two sets of K spaces in the multiple sets of echo data being opposite; and reconstructing an image based on the echo data filled in the K space.

Description

technical field [0001] Embodiments disclosed in the present invention relate to medical imaging technology, and more particularly to a method for acquiring and processing magnetic resonance data, a magnetic resonance imaging system and method. Background technique [0002] Magnetic resonance imaging (MRI) is a medical imaging modality that can obtain images of the human body without the use of X-rays or other ionizing radiation. MRI utilizes a magnet with a strong magnetic field to generate a main magnetic field B0. When the part of the human body to be imaged is positioned in the main magnetic field B0, the nuclear spins associated with the hydrogen nuclei in the human tissue are polarized, so that the tissue of the part to be imaged macroscopically generates a longitudinal magnetization vector. When the radio frequency field B1 intersecting the direction of the main magnetic field B0 is applied, the direction of proton rotation changes, so that the tissue at the imaging s...
