Abstract
En 中文
Ultrasound waves can be generated by various radiation sources, including X-rays, protons, electrons and electrical fields, through the rapid thermal expansions and contractions that occur when materials absorb deposited radiation energies. The ultrasound waves, which we refer to as ‘radiacoustic waves’, can be detected for imaging purposes. Radiacoustic imaging offers new imaging contrasts beyond traditional pulse–echo ultrasound. This Perspective provides an analysis of progress in radiacoustic imaging in recent years, focusing on biomedical and materials science applications. We explore the mechanisms behind radiacoustic imaging, highlight its current uses and challenges, and discuss potential advances to improve the effectiveness of radiacoustic imaging technologies across different fields. Radiacoustic imaging uses ultrasound waves generated by radiation energy deposition for imaging contrast. This Perspective highlights advances, mechanisms, and biomedical and materials science applications, and outlines challenges and opportunities for this emerging imaging technology.
