AI Technical Summary

Problems solved by technology

[0004] (1) There are measurement errors caused by different coils (such as head coils, abdominal coils, etc.), resulting in different coil sizes and test channel distributions in the coils
[0005] (2) It is impossible to judge the quality of the magnetic resonance imaging;
[0006] (3) The size of the phantom is small and the measurement range is small, so it is difficult to find the factors that affect the imaging of magnetic resonance equipment by the magnetic field of the equipment
[0007] To sum up, at present, the measurement error caused by the different size of the coil and the distribution of the test channels in the coil cannot judge the quality of the magnetic resonance imaging, and there is still a lack of effective solutions

Abstract

The invention discloses a magnetic resonance imaging quality control integrated die body, which improves the performance of test equipment. The magnetic resonance imaging quality control integrated die body comprises a die body outer shell and a die body inner shell, wherein the interiors of the die body outer shell and the die body inner shell are each of a cavity structure, the die body inner shell is arranged in the die body outer shell, a coil is arranged on the outer wall of the die body inner shell, and test units are evenly distributed in the coil.

Description

technical field [0001] The disclosure relates to the technical field of magnetic resonance imaging, in particular to an integrated phantom for magnetic resonance imaging quality control. Background technique [0002] Among the imaging parameters of magnetic resonance imaging equipment, parameters such as signal-to-noise ratio, geometric deformation, high resolution, layer thickness, low contrast, field layer uniformity, artifacts, MTF, T1 and T2 are important precise quality control items. [0003] At present, the phantom imaging measurement of the magnetic resonance equipment is to measure the imaging of the magnetic resonance equipment with coils and phantoms that are randomly equipped with the magnetic resonance equipment, such as head coils and abdominal coils. The phantom structure of the current magnetic resonance equipment has the following problems: [0004] (1) There are measurement errors caused by different coils (such as head coils, abdominal coils, etc.), resul...
