Embodiment 1
[0067] like figure 1 As shown, the specific steps of the multi-point accurate sampling method for brain tumors are as follows:
[0068] a. For patients with craniocerebral gliomas, the preoperative MRI data were extracted, and the core components were constructed using the ITK and MTK algorithms in 3D-slicer to delineate the lesions, and the Python package pyradiomics was used to perform radiomics The first-order and second-order features are extracted, and the radiomics features of each pixel unit are subjected to 3D reconstruction and spatial clustering, so as to realize the division of intra-tumor heterogeneity based on radiomics. The analysis divided the tumor into 3-5 different regions and performed coordinate extraction of representative sampling points for each region.
[0069] b. Integrate the patient's preoperative 3D reconstructed CT with ordinary MRI, formulate a navigation plan, demarcate the scope of tumor resection, and obtain the reference coordinates of the tu...
Embodiment 2
[0082] Multi-point precision sampling system for brain tumors, including:
[0083] Used to obtain MRI data within the tumor boundary;
[0084] It is used to extract MRI data and convert MRI data into first-order features, second-order features, shape features, and texture features;
[0085] It is used to carry out 3D reconstruction and spatial clustering of each radiomics feature to obtain a 3D topographic map of the cerebral cortex and realize the classification of tumor subregions;
[0086] It is used to use CT data and MRI data to make a navigation plan, demarcate the scope of tumor resection, obtain the reference coordinates of tumor boundaries and tumor entities, map them to the radiomics partition constructed by MRI, and obtain the center position coordinates and fault tolerance boundaries of each partition. coordinate interval;
[0087] It is used to import the reference coordinates of the tumor boundary and tumor entity into the AR device to remove tumor lesions;

Embodiment 3
[0095] like figure 2As shown in the figure, a laser positioning material acquisition device includes a bracket, a sliding device, a cross laser positioner 3, a specimen box 5, and a cutter. The sliding device is arranged opposite the specimen box 5, and the sliding device includes a vertical slide 2. The vertical slideway 2 is slidably connected, and the cutter is opposite to the specimen box 5 .
[0096] It also includes a cooling table 6 , and the specimen box 5 is arranged on the top of the cooling table 6 .
[0097] like Figure 4 As shown, the bracket is a square frame structure, which includes a fixed side 9, a slide side 10 and a movable side 11, the slide side 10 is a set of opposite sides, and one end of the two slide sides 10 is fixedly connected to the fixed side 9 respectively. , the two ends of the moving side 11 are slidably connected with the two slideway sides 10, and the sliding device is vertically arranged on the moving side and is slidably connected with...
