The early detection of breast cancer, particularly in dense breast tissues, faces significant challenges with traditional imaging techniques such as mammography. This study utilizes a Near-infrared Scan (NIRscan) probe and an advanced convolutional neural network (CNN) model to enhance tumor localization accuracy and efficiency. CNN processed data from 133 breast phantoms into 266 samples using data augmentation techniques, such as mirroring. The model significantly improved image reconstruction, achieving an RMSE of 0.0624, MAE of 0.0360, R of 0.9704, and Fuzzy Jaccard Index of 0.9121. Subsequently, we introduced a multitask CNN that reconstructs images and classifies them based on depth, length, and health status, further enhancing its diagnostic capabilities. This multitasking approach leverages the robust feature extraction capabilities of CNNs to perform complex tasks simultaneously, thereby improving the model's efficiency and accuracy. It achieved exemplary classification accuracies in depth (100%), length (92.86%), and health status, with a perfect F1 Score. These results highlight the promise of NIRscan technology, in combination with a multitask CNN model, as a supportive tool for improving real-time breast cancer screening and diagnostic workflows.
乳腺癌的早期检测,尤其是在乳腺致密组织中,传统成像技术(如乳腺钼靶摄影)面临重大挑战。本研究利用近红外扫描(NIRscan)探头和先进的卷积神经网络(CNN)模型,以提高肿瘤定位的准确性和效率。CNN使用数据增强技术(如镜像)将来自133个乳腺模型的数据处理成266个样本。该模型显著改善了图像重建,均方根误差(RMSE)为0.0624,平均绝对误差(MAE)为0.0360,相关系数(R)为0.9704,模糊杰卡德指数(Fuzzy Jaccard Index)为0.9121。随后,我们引入了一种多任务CNN,它可以重建图像并根据深度、长度和健康状况对其进行分类,进一步增强其诊断能力。这种多任务方法利用CNN强大的特征提取能力同时执行复杂任务,从而提高模型的效率和准确性。它在深度(100%)、长度(92.86%)和健康状况方面取得了优异的分类准确率,F1分数完美。这些结果凸显了NIRscan技术与多任务CNN模型相结合,作为改善实时乳腺癌筛查和诊断工作流程的辅助工具的前景。
