This paper reviews the theories and applications of electromagnetic⁻acoustic (EMA) techniques (covering light-induced photoacoustic, microwave-induced thermoacoustic, magnetic-modulated thermoacoustic, and X-ray-induced thermoacoustic) belonging to the more general area of electromagnetic (EM) hybrid techniques. The theories cover excitation of high-power EM field (laser, microwave, magnetic field, and X-ray) and subsequent acoustic wave generation. The applications of EMA methods include structural imaging, blood flowmetry, thermometry, dosimetry for radiation therapy, hemoglobin oxygen saturation (SO₂) sensing, fingerprint imaging and sensing, glucose sensing, pH sensing, etc. Several other EM-related acoustic methods, including magnetoacoustic, magnetomotive ultrasound, and magnetomotive photoacoustic are also described. It is believed that EMA has great potential in both pre-clinical research and medical practice.
本文综述了电磁声（EMA）技术的理论和应用，该技术属于电磁混合技术的更广泛领域，涵盖光致光声、微波致热声、磁调制热声和 X 射线致热声。该理论涵盖了高功率电磁场（激光、微波、磁场和 X 射线）的激发以及随后的声波产生。EMA 方法的应用包括结构成像、血流测量、测温、放射治疗剂量学、血红蛋白氧饱和度（SO₂）传感、指纹成像和传感、葡萄糖传感、pH 传感等。还描述了其他几种与电磁相关的声学方法，包括磁声、磁动超声和磁动光声。相信 EMA 在临床前研究和医学实践中都具有巨大的潜力。
