超声暴露的安全性对于患者的健康非常重要。高频（1-10 MHz）超声波被生物组织高度吸收，对内脏器官的治疗效果有限。本文介绍了一种用于生物组织超声处理的低频（20-100 kHz）超声换能器的开发和应用结果。使用由虚拟和物理双胞胎组成的数字双胞胎的方法，已经开发出一种超声换能器，其发射穿透更深生物组织的聚焦超声信号。为此目的，该换能器的环形端面不仅由主纵向振动模式激励，这是迄今为止使用的平坦端面换能器的典型模式，而且还由更高模式的径向振动激励。虚拟孪生模拟显示，由环形换能器发射的由更高振动模式激发的声信号被集中成更窄且更精确的声波，该声波更深地穿透到生物组织中，并且仅影响身体的待治疗部分，而不是整个身体。
The safety of ultrasound exposure is very important for a patient’s well-being. High-frequency (1–10 MHz) ultrasound waves are highly absorbed by biological tissue and have limited therapeutic effects on internal organs. This article presents the results of the development and application of a low-frequency (20–100 kHz) ultrasonic transducer for sonication of biological tissues. Using the methodology of digital twins, consisting of virtual and physical twins, an ultrasonic transducer has been developed that emits a focused ultrasound signal that penetrates into deeper biological tissues. For this purpose, the ring-shaped end surface of this transducer is excited not only by the main longitudinal vibrational mode, which is typical of the flat end surface transducers used to date, but also by higher mode radial vibrations. The virtual twin simulation shows that the acoustic signal emitted by the ring-shaped transducer, which is excited by a higher vibrational mode, is concentrated into a narrower and more precise acoustic wave that penetrates deeper into the biological tissue and affects only the part of the body to be treated, but not the whole body.
