The difficulty or cost of obtaining data or labels in applications like medical imaging has progressed less quickly. If deep learning techniques can be implemented reliably, automated workflows and more sophisticated analysis may be possible in previously unexplored areas of medical imaging. In addition, numerous characteristics of medical images, such as their high resolution, three-dimensional nature, and anatomical detail across multiple size scales, can increase the complexity of their analysis. This study employs multiconvolutional transfer learning (MCTL) for applying deep learning to small medical imaging datasets in an effort to address these issues. Multiconvolutional transfer learning is a model based on transfer learning that enables deep learning with small datasets. In order to learn new features on a smaller target dataset, an initial baseline is used in the transfer learning process. In this study, 3D MRI images of brain tumors are classified using a convolutional autoencoder method. In order to use unenhanced Magnetic Resonance Imaging (MRI) for clinical diagnosis, expensive and invasive contrast-enhancing procedures must be performed. MCTL has been shown to increase accuracy by 1.5%, indicating that small targets are more easily detected with MCTL. This research can be applied to a wide range of medical imaging and diagnostic procedures, including improving the accuracy of brain tumor severity diagnosis through the use of MRI.
在医学成像等应用中,获取数据或标签的难度或成本进展较慢。如果可以可靠地实施深度学习技术,那么自动化工作流程和更复杂的分析可能在医学成像的以前未探索的领域成为可能。此外,医学图像的许多特征,例如它们的高分辨率、三维性质和跨多个大小尺度的解剖细节,可以增加其分析的复杂性。本研究采用多卷积迁移学习(MCTL)将深度学习应用于小型医学成像数据集,以解决这些问题。多卷积迁移学习是一种基于迁移学习的模型,可用于处理小型数据集的深度学习。为了在较小的目标数据集上学习新特征,在迁移学习过程中使用初始基线。在这项研究中,使用卷积自动编码器方法对脑肿瘤的 3D MRI 图像进行分类。为了在临床诊断中使用未增强的磁共振成像(MRI),必须进行昂贵且有创的对比增强程序。研究表明,MCTL 可以将准确率提高 1.5%,这表明 MCTL 可以更轻松地检测到小目标。这项研究可以应用于广泛的医学成像和诊断程序,包括通过使用 MRI 提高脑肿瘤严重程度诊断的准确性。
