HIFU治疗系统焦域温度的检测方法

Detections of the Focal Regions Temperature for High Intensity Focused Ultrasound

高强度聚焦超声(HIFU)是近年来迅速发展的肿瘤治疗技术,随着技术的不断成熟,临床应用也越来越广泛,其治疗原理是将高强度的超声能量聚焦在靶区肿瘤组织,焦点区域在极短的时间内产生高温,从而使肿瘤组织发生凝固性坏死,达到治疗目的。HIFU作为一种热消融疗法,需要有良好的温度测量技术来保证治疗的安全和疗效。该文针对目前国内外已有的焦域温度检测方法做简单阐述。

As a tumor thermal ablation technology in cancer therapy, HIFU （High Intensity Focused Ultrasound） has been developed rapidly in recent years. With the technology becoming more and more mature, it’s clinical application is becoming more and more widely. In HIFU therapy, the high-intensity ultrasound energy is focused in the target tumor tissue, generating heat within very short time, causing coagulation necrosis, so that the effect of the treatment is achieved. To ensure safe and therapeutic efficacy, HIFU therapy needs to be properly monitored by medical imaging, and temperature in the target has to be precisely measured, this article is based on the current domestic and foreign detection methods of the focal region temperature.
