Problems solved by technology

The inventors found that because there are no relevant technical standards and norms for magnetic resonance DTI imaging technology, and there is no specific research on the anisotropy parameters of magnetic resonance DTI imaging technology, so there is a lack of means and methods for its imaging quality detection and control

Abstract

The invention provides a magnetic resonance diffusion tensor imaging quality control comprehensive test phantom. The magnetic resonance diffusion tensor imaging quality control comprehensive test phantom comprises a brain white matter fiber bundle simulation area located on the upper portion and an imaging quality evaluation test area located on the lower portion. The brain white matter fiber bundle simulation area comprises a first shell, a test layer is arranged in the first shell, the test layer is filled with gel, and the gel is used for wrapping a fiber material to construct different binding densities and directions so as to form different hydrogen proton dispersion gradient coefficients to simulate the actual brain white matter fiber bundle trend and distribution of the human brain;the imaging quality evaluation test area comprises a second shell, and cylinders filled with the gel with set density are arranged in the second shell and used for simulating magnetic resonance to image soft tissues; four cylinders with set diameters are arranged in the second shell, each cylinder is filled with the gel with set density and granulated sugar, and a magnetic resonance diffusion tensor imaging model used for evaluating the signal-to-noise ratio and the apparent diffusion coefficient is constructed.

Description

technical field [0001] The disclosure belongs to the field of testing devices for magnetic resonance diffusion tensor imaging DTI (Diffusion Tensor Magnetic Resonance Imaging; DTI), in particular to a comprehensive test phantom for quality control of magnetic resonance diffusion tensor imaging. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Magnetic resonance diffusion tensor imaging (DTI) is a medical imaging technique for morphological and functional imaging of human brain white matter fiber tracts, which is used to detect and study the morphology and related lesions of human brain white matter fiber tracts. The inventors found that since there are no relevant technical standards and norms for magnetic resonance DTI imaging technology, and there is no specific research on the anisotropy parameters of magnetic resonance DTI imaging tech...
