Embodiment 1

[0025] Refer to attached figure 1 - attached figure 2 , the present embodiment provides a technical solution: a phantom for MR-DTI includes a phantom 100 and a capillary channel 200 arranged in the phantom 100, the bottom of the phantom 100 is sealed with a liquid reservoir 300, the capillary channel 200 includes an imaging capillary 220 and a restrictive capillary 230, one end of the imaging capillary 220 passes through the upper part of the phantom 100, and one end of the imaging capillary 220 is away from the upper part of the phantom 100 One end of the restrictive capillary 230 is communicated with, and the end of the capillary capillary 230 away from the imaging capillary 220 is in communication with the reservoir 300, and the capillary imaging 220 is used to simulate the distribution of cerebral blood vessels or nerve fibers. The capillary tube 230 is arranged vertically, and the end of the capillary tube 230 connected to the capillary imaging tube 220 is lower than th...

Embodiment 2

[0035] Refer to attached figure 1 - attached figure 2 , the other structure of this embodiment is the same as that of Embodiment 1, the difference is that: a thin liquid storage tube 210 is arranged between the through hole 410 and the imaging thin tube 220, and one end of the thin liquid storage tube 210 is connected to the The other end of the through hole 410 is in sealing connection with one end of the imaging thin tube 220. The liquid storage thin tube 210 is arranged in a vertical tubular shape, and the end of the liquid storage thin tube 210 away from the through hole 410 is connected to the end of the imaging thin tube 220. One-piece molding setup. The middle section of the thin liquid storage tube 210 is provided with a liquid storage bin 211, the end of the liquid storage bin 211 away from the through hole 410 is higher than the highest point of the imaging thin tube 220, and the length of the inner diameter of the liquid storage bin 211 is The middle part reaches...

Abstract

The invention relates to the technical field of diffusion tensor imaging, in particular to a phantom for MR-DTI, comprising a phantom and a capillary channel arranged in the phantom, the bottom of the phantom is sealed with a liquid reservoir, and the capillary channel It includes an imaging thin tube and a flow-limiting thin tube. One end of the imaging thin tube passes through the upper part of the phantom, and the end of the imaging thin tube far away from the upper part of the phantom is connected to one end of the limiting flow thin tube. The liquid pool is connected, and the imaging capillary is used to simulate the distribution of cerebral blood vessels or nerve fibers. It has the advantage of being able to observe the diffusion in all directions of the phantom, and can obtain more accurate MRI diffusion tensor imaging results.

Description

technical field [0001] The invention belongs to the technical field of diffusion tensor imaging, in particular to a phantom for MR-DTI. Background technique [0002] Diffusion tensor imaging (DTI), a new method of characterizing brain structure, is a specialized form of magnetic resonance imaging (MRI). Magnetic resonance diffusion tensor imaging (MR-DTI) is the development and deepening of diffusion weighted imaging (DWI), and is currently the only non-invasive examination method that can effectively observe and track white matter fiber tracts. By 2015, it will be mainly used for the observation and tracking of the brain, especially the white matter tracts, the research of brain development and brain cognitive function, the pathological changes of brain diseases, and the preoperative planning and postoperative evaluation of brain surgery. However, the current phantom container can only observe the disordered Brownian motion of the overall uniform water phantom, and cannot ...
