摘要
该文阐述了超分辨率超声成像技术的研究进展,分别详细介绍了该成像技术在实现过程中包含的每个环节步骤(超声发射扫描、波束合成、壁滤波、微泡定位和追踪等),并结合已有文献总结了现存问题和潜在解决方案。针对相关临床应用和需求场景,该文重点讨论了超分辨成像技术的4个未来发展方向,包括3D超分辨率成像、产品化的实现、无造影剂的超分辨和人工智能技术。此外,该文介绍了基于超分辨成像功能的多个定量参数的计算方法,并通过仿真展示了不同参数(分形维数、方向熵和圆方差)的计算结果和相关性。
This paper elaborates on the research progress of super-resolution ultrasound imaging technique,detailing each step involved in the implementation process of this technology(ultrasound transmission and scanning,beamforming,clutter filtering,microbubble localization and tracking,etc.),and summarizes existing problems and potential solutions based on existing literature.Targeting relevant clinical applications and demand scenarios,the paper focuses on four future directions of super-resolution imaging technology,including 3D super-resolution imaging,realization of productization,contrast-free super-resolution,and artificial intelligence(AI)technology.In addition,the paper introduces the calculation methods of multiple quantitative parameters based on the function of super-resolution imaging,and demonstrates the calculation results and correlations of different parameters(fractal dimension,directional entropy,and circular variance)through simulations.
