High Intensity Focused ultrasound (HIFU) is a technique where mechanical energy is concentrated in a small volume. This concentration can be used to induce several bio-effects in biological tissue including absorption, radiation-force streaming or cavitation. Magnetic resonance imaging (MRI) provides a precise volumetric image reconstruction and has become the preferred modality to guide HIFU since MRI can be used to monitor the absorption effects induced by HIFU. The combination of MRI and HIFU is known as MRgHIFU. Even if HIFU has proven being an effective option for therapeutic applications such as the treatment of uterine fibroids, a considerable amount of basic research has to be conducted to overcome challenges as reaching targets behind the rib cage and compensate organ movement.

高强度聚焦超声（HIFU）是一种将机械能集中在小体积中的技术。该浓度可用于在生物组织中诱导若干生物效应，包括吸收、辐射力流或空化。 磁共振成像（MRI）提供精确的体积图像重建，并已成为引导HIFU的首选模式，因为MRI可用于监测HIFU诱导的吸收效应。MRI和HIFU的组合被称为MRgHIFU。即使HIFU已被证明是治疗应用的有效选择，如治疗子宫肌瘤，也必须进行大量的基础研究，以克服达到胸腔后面的目标和补偿器官运动的挑战。
