Brain model and preparation methods thereof

Abstract

The invention relates to a brain model and preparation methods thereof. The brain model comprises a healthy brain model, a brain model provided with a hemorrhagic spot model and a brain model provided with an ischemic spot model. The invention also provides corresponding manufacturing methods. Meanwhile, different perfusates are designed according to the internal structure of the brain and comprise a cerebrospinal fluid perfusate, a grey matter perfusate, a white matter perfusate, a cerebellum perfusate, a brainstem perfusate, a hemorrhagic point perfusate and an ischemic point perfusate. The invention also provides corresponding preparation methods. According to the brain model obtained through configuration, the dielectric constant and the loss angle of the brain model are close to true values, the separation degree is good, and it can be ensured that layers cannot be fused or confused.

Description

Technical field

[0001] The present invention relates to microwave medical imaging, human model, ischemia, bleeding stroke monitoring technology, and is specifically a brain model and a preparation method thereof. Background technique

[0002] The brain model formulation method of domestic and foreign research is mainly divided into two types:

[0003] The first is to use solid state raw materials, such as corn flour, wheat flour, etc. For the first configuration method, this type of brain model is very fast, the dielectric constant is unstable, and the production process is complex.

[0004] The second is to use liquid raw materials, such as saffron oil, kerosene, etc.. For the second production method, first, in this way, most of the simple one, two ratios, very few people, have studied the complex model of multi-organizational. Second, there is no discussion of the separation of the model, because when making complex brain models, there will be a variety of different organizati...
