Ultrasound signal processing plays an important role in medical image analysis. Embedded ultrasonography systems with low power consumption and high portability are suitable for disaster rescue, but due to the difficulty of ultrasonic signal recognition, operators need to have strong professional knowledge, and it is not easy to deploy ultrasonography systems in areas with relatively weak infrastructures. In recent years, with the continuous development in the field of deep learning and artificial intelligence, lightweight convolutional neural networks have brought new opportunities for ultrasound signal processing. This paper focuses on investigating lightweight convolutional neural networks applied to ultrasound signal classification. Combined with the characteristics of ultrasound signals, this paper provides a detailed review of lightweight algorithms from two perspectives: model compression and operational optimization. Among them, model compression deals with the overall framework to reduce network redundancy, and the latter aims at the lightweight design of the basic operational module "convolution" in the network. The experimental results of some classical models and algorithms on the ImageNet dataset are summarized. Through the comprehensive analysis, we present some problems and provide an outlook on the future development of lightweight techniques for ultrasound signal classification.
超声信号处理在医学图像分析中起着重要作用。低功耗、高便携性的嵌入式超声检查系统适用于灾难救援,但由于超声信号识别困难,操作人员需要具备较强的专业知识,并且在基础设施相对薄弱的地区部署超声检查系统并不容易。近年来,随着深度学习和人工智能领域的不断发展,轻量级卷积神经网络为超声信号处理带来了新机遇。本文着重研究应用于超声信号分类的轻量级卷积神经网络。结合超声信号的特点,本文从模型压缩和运算优化两个角度对轻量级算法进行了详细综述。其中,模型压缩针对整体框架以减少网络冗余,后者则针对网络中基本运算模块“卷积”的轻量级设计。总结了一些经典模型和算法在ImageNet数据集上的实验结果。通过综合分析,我们提出了一些问题,并对超声信号分类轻量级技术的未来发展进行了展望。
