Brain tumors are complex clinical lesions with diverse morphological characteristics, making accurate segmentation from MRI scans a challenging task. Manual segmentation by radiologists is time-consuming and susceptible to human error. Consequently, automated approaches are anticipated to accurately delineate tumor boundaries and quantify tumor burden, addressing these challenges efficiently. The presented work integrates a convolutional block attention module (CBAM) into a deep learning architecture to enhance the accuracy of MRI-based brain tumor segmentation. The deep learning network is built upon a VGG19-based U-Net model, augmented with depthwise and pointwise convolutions to improve feature extraction and processing efficiency during brain tumor segmentation. Furthermore, the proposed framework enhances segmentation precision while simultaneously incorporating tumor area measurement, making it a comprehensive tool for early-stage tumor analysis. Several qualitative assessments are used to assess the performance of the model in terms of tumor segmentation analysis. The qualitative metrics typically analyze the overlap between predicted tumor masks and ground truth annotations, providing information on the segmentation algorithms' accuracy and dependability. Following segmentation, a new approach is used to compute the extent of segmented tumor areas in MRI scans. This involves counting the number of pixels within the segmented tumor masks and multiplying by their area or volume. The computed tumor areas offer quantifiable data for future investigation and clinical interpretation. In general, the proposed methodology is projected to improve segmentation accuracy, efficiency, and clinical relevance compared to existing methods, resulting in better diagnosis, treatment planning, and monitoring of patients with brain tumors.
脑肿瘤是具有多样形态特征的复杂临床病变,因此从磁共振成像(MRI)扫描中进行准确分割是一项具有挑战性的任务。放射科医生进行的手动分割既耗时又容易出现人为误差。因此,人们期望自动化方法能够准确勾勒肿瘤边界并量化肿瘤负荷,从而有效应对这些挑战。本文提出的工作将卷积块注意力模块(CBAM)集成到深度学习架构中,以提高基于MRI的脑肿瘤分割的准确性。深度学习网络基于基于VGG19的U-Net模型构建,并通过深度卷积和逐点卷积进行增强,以提高脑肿瘤分割过程中的特征提取和处理效率。此外,所提出的框架在提高分割精度的同时,还纳入了肿瘤面积测量,使其成为早期肿瘤分析的综合工具。使用了几种定性评估方法来评估模型在肿瘤分割分析方面的性能。定性指标通常分析预测的肿瘤掩码与真实标注之间的重叠情况,提供有关分割算法准确性和可靠性的信息。分割后,采用一种新方法来计算MRI扫描中分割出的肿瘤区域的范围。这涉及计算分割出的肿瘤掩码内的像素数量,并乘以其面积或体积。计算出的肿瘤面积为未来的研究和临床解读提供了可量化的数据。总体而言,与现有方法相比,预计所提出的方法将提高分割的准确性、效率和临床相关性,从而实现对脑肿瘤患者更好的诊断、治疗规划和监测。
