Аннотация:Radiation force is a universal phenomenon in anywave motion where the wave energy produces a tatic or transient force on the propagation medium. The theory of acoustic radiation force (ARF) dates back to the early 19th century. In recent years,there has been an increasing interest in the biomedical applications of ARF. Following a brief history of acoustic radiation force, this paper describes a concise theory of ARF under fourphysical mechanisms of radiation force generation in tissue-like media. These mechanisms are primarily based on the dissipation of acoustic energy of propagating waves, the reflection of theincident wave, gradients of the compressional wave speeds, and the spatial variations of energy density in standing acoustic waves. Examples describing some of the practical applications of ARF under each mechanism are presented. This paper concludes with a discussion on selected ideas for potential future applications of ARF in biomedicine
