创新超声成像技术: biomedical 应用
This book provides an understanding of ultrasound imaging principles and how the field is evolving to better probe living systems. Today, widely-used imaging systems visualize structures and blood flow within the body in real-time. Signal analysis, hardware and contrast agent innovations are extending the capacity of ultrasound to assess tissue elasticity, to enable three-dimensional viewing of moving structures and to detect vessels smaller than the wavelength-limited resolution. Techniques are also being designed so that we are less impeded by bones in the sound path, as well as to combine light and sound to detect optically-absorbent structures within the body. After an introductory chapter reviewing the key basic concepts, each chapter presents a detailed explanation focusing on a specific set of key principles and then shows the related techniques in each domain that are currently being refined to evaluate living systems in greater depth.
这本书提供了超声成像原理的理解,以及该领域如何发展以更好地探查生物系统。如今,广泛使用的成像系统能够在实时状态下可视化人体内的结构和血液流动。信号分析、硬件及对比剂的创新正在扩展超声的能力,以便评估组织弹性,实现对运动结构的三维观察,并检测比波长限制分辨率小得多的血管。同时也在设计技术以减少骨骼在声波路径中阻碍的影响,以及结合光线与声音来探测人体内的光学吸收结构。 在介绍章节回顾了关键基本概念之后,每章都提供了一种详细解释,重点介绍了特定原则集,并展示了当前正被精炼的技术,这些技术用于更加深入地评估生物系统。
