摘要:

脑癌的诊断严重依赖医学成像技术,其中MRI是最常用的。有必要对MRI图像进行脑肿瘤的自动分割。本项目计划构建一个基于U-Net的MRI算法。将残差网络与用于增强上下文信息的模块相结合,并在网络中加入空洞空间卷积池化金字塔进行处理。使用cancer imaging archives提供的脑胶质瘤MRI图像数据集进行了实验验证。采用基于加权最小二乘滤波器的多尺度分割方法完成了脑肿瘤的3D重建。从而进一步提高了三维重建的准确度。实验表明,该算法获得的局部纹理特征与激光扫描获得的特征相似。通过使用U-Net方法改进算法,获得了0.9851的准确率。该方法显著提高了图像分割的精度,并提升了图像分类的效率。

英文摘要:

The diagnosis of brain cancer relies heavily on medical imaging techniques, with MRI being the most commonly used. It is necessary to perform automatic segmentation of brain tumors on MRI images. This project intends to build an MRI algorithm based on U-Net. The residual network and the module used to enhance the context information are combined, and the void space convolution pooling pyramid is added to the network for processing. The brain glioma MRI image dataset provided by cancer imaging archives was experimentally verified. A multi-scale segmentation method based on a weighted least squares filter was used to complete the 3D reconstruction of brain tumors. Thus, the accuracy of three-dimensional reconstruction is further improved. Experiments show that the local texture features obtained by the proposed algorithm are similar to those obtained by laser scanning. The algorithm is improved by using the U-Net method and an accuracy of 0.9851 is obtained. This approach significantly enhances the precision of image segmentation and boosts the efficiency of image classification.
