specific Embodiment
[0038] A dynamic magnetic resonance test phantom system, including a volume of 160×160×160mm 3 The dynamic test assembly 5, a cylindrical hollow fixed housing 1 with a diameter of 240 mm and a height of 160 mm, and a phantom support member 2.
[0039] The two-channel test component is 80×80×80mm 3 The PMMA solid cube with a volume of 60×60×60mm 3 The upper, left, and lower surfaces of the two-channel solid cube 501 have two semicircular rectangular grooves with a length of 20mm and a spacing of 20mm along the Y, Z, and X directions, and they are respectively along the X, Y, and Y directions. Two semicircular rectangular grooves with a length of 20 mm and a spacing of 20 mm are opened to connect the rectangular grooves along the Y, Z, and X directions. In this embodiment, the diameter of the semi-circular rectangular grooves is 5 mm, and the same applies below. Correspondingly, the six working surfaces of the two-channel peripheral component 502 with a thickness of 10 mm are groov...

Description
Technical field [0001] The invention relates to a magnetic resonance imaging (MRI) system, and more specifically, to a dynamic magnetic resonance test phantom system. Background technique [0002] With the development of imaging technology, medical magnetic resonance imaging technology has been widely used in clinical fields with its own unique advantages. MRI can provide high-resolution static images in soft tissue imaging and other diagnostics to observe the lesions of the human body, which greatly improves the efficiency and accuracy of diagnosis. However, simple structural images cannot clarify the pathological process well, especially vascular diseases. In such diseases, static images only show the shape of blood vessels at a certain moment and have no practical research significance. In view of the limitations of static images in the diagnosis of cerebrovascular diseases, and to ensure efficient and high-precision imaging guarantees for MRI equipment in practical applicati...
