高强度聚焦超声 (HIFU) 是用于描述高功率超声聚焦束用于治疗效果的术语。该技术有时也称为聚焦超声手术 (FUS)。现在许多不同的 HIFU 治疗的共同特征是需要提供一个光束,其中能量足以仅在病灶体积内产生生物变化。除了少数例外,其目的是诱导不可逆的损伤,尽管在某些应用中,例...

一、简介 高强度聚焦超声 (HIFU) 或聚焦超声手术 (FUS) 治疗软组织肿瘤依赖于产生紧密聚焦的超声场,其中焦点处的强度足以引起不可逆的细胞损伤。主要的生物损伤机制是加热[引文1 ]。目前对细胞水平热损伤的大部分理解都源自体外和全身高温研究。一般来说,温度每升高一度高于 43...
High-intensity focussed ultrasound [HIFU, synonym: focussed ultrasound surgery (FUS)] is an established therapeutic method for the noninvasive or minimally invasive thermoablation of organ lesions through focussed ultrasound beams. By integrating HIFU transducers into diagnostic MR scanners, HIFU treatment...
HiFU treatment, also known as high-frequency focused ultrasound (fUS) and MRI-guided focused ultrasound (MRgFUS), is performed in an MRI machine.HiFU treatment generates ultrasound waves that are thousands of times more intense than diagnostic ultrasound, with the energy focused on a tiny area....

For pancreatic tumor ablation monitoring, FUS was used to induce HIFU thermal ablation and tissue motion at the same time, allowing HMI monitoring without interrupting tumor ablation. All pancreases were excised immediately after sonication for histological evaluation. The obtained HMI displacement images...
High intensity focused ultrasound (HIFU), which is also known as focused ultrasound surgery (FUS), is a prime example of high-energy therapeutic ultrasound [1], [2]. HIFU systems produce a focused ultrasound field whose intensity can reach over 10,000 W/cm2 in order to induce localized ...
