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）是一种机械能集中在少量体积的技术。该浓度可用于诱导生物组织中的多种生物效应，包括吸收，辐射冲流或空化。 磁共振成像（MRI）提供了精确的体积图像重建，并已成为指导HIFU的首选模态，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。即使事实证明HIFU是治疗子宫肌瘤等治疗应用的有效选择，也必须进行大量的基础研究，以克服挑战，因为挑战在肋骨笼子背后达到目标并补偿器官运动。
