Embodiment Construction

[0038] The relevant technical contents not mentioned below can adopt or learn from the prior art.

[0039] A small desktop magnetic resonance quality control comprehensive test phantom, the phantom includes a shell and a test layer, and is composed of a cylindrical shell and three relatively independent test areas. Module fastening holes are provided at the same position of the test area, and the test area is fastened to the long rod bolt through the module fastening hole, and the long rod bolt is covered with a sleeve. The test area is installed in the shell and fixed on the shell; the test area includes a human brain simulation test area, a fiber bundle test area, and a basic imaging quality test area. The inside of the casing and the test area are filled with a special test solution for magnetic resonance, specifically copper sulfate pentahydrate, sodium chloride and distilled water, or copper sulfate pentahydrate, nickel chloride and distilled water.

Abstract

The invention discloses a comprehensive test phantom for controlling the quality of diffusion tensor magnetic resonance imaging, which comprises a casing, wherein a test layer is arranged in the casing and is filled with a test solution. The comprehensive test phantom is characterized by further comprising a fiber bundle test region, a human brain simulation test region and a basic imaging quality test region; a fiber bundle test layer comprises three groups: the first group comprises two fiber bundle groups, wherein each group of fiber bundles is positioned on the same plane; the second group is a fiber bundle group; an included angle is formed between a straight line where each fiber bundle is positioned and a long axis of the phantom casing; the third group comprises helix tubes; and fiber bundles are arranged in the helix tubes. Compared with the prior art, the comprehensive test phantom has the advantages of multiple test parameters, high precision, high simulation degree of white matters of human brain and convenience for use.

Description

technical field [0001] The invention relates to a test device for magnetic resonance diffusion tensor imaging DTI (Diffusion Tensor Magnetic Resonance Imaging; DTI), in particular to a special quality control test phantom and brain white matter for magnetic resonance human brain white matter diffusion tensor imaging. Fiber bundle simulation phantom. Background technique [0002] 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. Since there are no relevant technical standards and specifications for magnetic resonance DTI imaging technology, there are no means and methods for its imaging quality inspection and control. Contents of the invention [0003] In view of the above problems, the present invention provides a comprehensive test phantom for the qu...
