Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] Such as figure 2 As shown, the single-sided magnet magnetic resonance system described in the solution of the present invention includes a workstation, a nuclear magnetic resonance spectrometer, a magnet, a radio frequency system, and a translation platform. The workstation is connected with the nuclear magnetic resonance spectrometer, sends commands to control the radio frequency pulse sequence and completes real-time data processing of the collected magnetic resonance signals.

[0048] The workstation is also connected with the displacement platform to control the displacement platform to move to the designated position.

[0049] The translation platform, the magnet and the RF coil are fixed by a mechanical structure, that is, when the translation platf...

Abstract

The invention discloses a fat quantification method and system based on unilateral magnet magnetic resonance. The method comprises the following steps: S0, acquiring magnetic resonance signals of multiple positions through a mobile displacement table; S1, dividing an excitation area into N sub-areas along the moving direction, namely R1, R2, R3, and the like, RN; S2, determining the signal weightomega n on each sub-area Rn; S3, generating a projection matrix A; S4, solving the following optimization problems min Ap-P2+P1, wherein P is greater than or equal to 0 and less than or equal to 1; and S5, calculating distribution of fat in different areas. According to the method and system, the problem of inaccurate fat detection caused by non-ideal excitation areas can be solved.

Description

technical field [0001] The invention relates to the technical field of magnetic resonance, in particular to a fat quantification method and a system thereof by single-side magnet magnetic resonance. Background technique [0002] Among the traditional medical equipment, the technical means that can be used for the detection of fatty liver mainly include ultrasound, magnetic resonance and puncture, but each has its own limitations, such as: a) Ultrasound: traditional ultrasound detection equipment can only perform qualitative measurements, and cannot Meet the detection requirements when the fat content is less than 30%; the other is the quantitative detection of fatty liver and liver fibrosis based on ultrasound. The main limitation is that it is easily affected by insufficient ultrasound penetration, and the detection success rate in obese patients is low. b) Magnetic resonance, using magnetic resonance Dixon technology to quantify fat and magnetic resonance elastography (Mag...
