Embodiment 1

[0044] Embodiment one, about filler

[0045] On the basis of the above-mentioned inventive concept, it is not difficult to find a suitable gel. Common gelatin substances include gelatin and agarose.

[0046] gelatin

[0047] Also known as gelatin or fish glue, it is transliterated from the English name Gelatin. Gelatin is a hydrolyzate of collagen, a protein gel extracted from fish fat and fish skin. It is a fat-free, high-protein, and cholesterol-free, and is a natural and nutritious food thickener. Gelatin is a colorless to light yellow solid, in the form of powder, sheet or block, insoluble in water, but when soaked in water, it can absorb 5 to 10 times of water and expand and soften, if heated, it will dissolve into a colloid, cooling When the temperature is below 35-40°C, it becomes a gel. However, if the aqueous solution is boiled for a long time, its properties will change due to decomposition, and it will no longer form a gel after cooling. When the warm gelatin s...

Embodiment 2

[0081] Embodiment two, about the device

[0082] Such as Figure 4 and Figure 5 As shown, the gel mold body 5 is used to accommodate the jelly gel-like filler 1. In order to ensure the imaging quality during the detection process, the mold body 5 can be made of PMMA (acrylic) material or other materials such as glass.

[0083] In addition to the above method of directly injecting liquid into the gel, the target test liquid can also be tested by placing the target test liquid in the test liquid container, such as a test tube, and placing the test liquid container in the gel. liquid for target imaging. The above-mentioned test solution container must be put in before the gel is completely solidified, otherwise the gel cannot completely wrap the test solution container, which will easily cause air bubbles, which is not conducive to imaging.

[0084] A plurality of test liquid containing parts can be equipped in one phantom 5 to realize magnetic resonance imaging of multiple t...

Abstract

The invention provides a gel mold and a preparation method and application thereof, a filler of the gel mold is in a jelly gel state, the filler is a uniform mixture of a water mold filling solution and a gel substance, and the gel substance is gelatin or agarose. The gel mold is prepared from low-cost materials and applied, and the technical problem that in the prior art, injected blood cannot beeffectively prevented from being dissolved in filling liquid, and therefore a cerebral hemorrhage model of a human body cannot be effectively simulated is solved.

Description

technical field [0001] The invention relates to the testing field of magnetic resonance imaging, and relates to a gel mold, an application and a mold body. Background technique [0002] Medical magnetic resonance imaging device (MRI) is a kind of equipment used in the field of medical imaging, which has the characteristics of complex technology and high price. With the advancement of technology, MRI has more prominent advantages in today's medical diagnosis. The basic principle of MRI is to excite biological tissue through different radio frequency pulse sequences, use the gradient field to spatially locate the tissue, and use the receiving coil to detect the relaxation time and proton density information of the tissue to form a tissue image. [0003] In the magnetic resonance system, different sequences are used to scan it, and the imaging of the blood part can be clearly distinguished, thereby verifying the correctness of the scanning sequence. MRI tests for cerebral hem...
