Leverage the power of US and MR

Now you can work with image-guided precision thanks to built-in US and MR capabilities. The HIFU system and coil elements are integrated in the Sonalleve table. Ultrasound waves are focused onto the target volume, ablating the lesion without affecting nearby tissue. The process is monitored with real-time temperature-sensitive MRI.

MR guidance: good news for skin

Sonalleve MR-HIFU is designed for intact skin. High Intensity Focused Ultrasound (HIFU) is used to heat and coagulate tissue deep inside the body. MRI measures temperature changes within the human body, making it useful for planning and monitoring thermal ablation processes such as HIFU.

Monitor temperature in real time

The MR scanner acquires temperature-sensitive images for monitoring local heat distribution. The Real-TI bi-directional interface enables real-time data transfer for directing the MR system through the Sonalleve console and retrieving images.

Make the most of each treatment

Sonalleve MR-HIFU facilitates efficient treatment with volumetric heating. To heat large volumes, the focused ultrasound beam is rapidly scanned over the volume to be ablated, creating an ellipsoidal, homogeneous thermal lesion. You can adjust it up to 16mm wide and 40mm length and achieve a macroscopic ablation zone within seconds. Large target volumes are covered with multiple heating events.

Stay informed with ongoing feedback. Real-time temperature readings automatically optimize HIFU delivery parameters, creating a feedback loop to better assess and compensate for local variations in tissue properties such as inhomogeneous absorption, attenuation, perfusion, and diffusion.

Work quickly and efficiently

Say hello to DIrect Skin Cooling (DISC). It keeps your patient’s skin at a constant temperature. Integrated into the ultrasound window, this device provides a heat sink by circulating cooled water between two membranes. To enhance cooling efficiency, patients are positioned directly onto the membrane. Most patients won’t require a gel pad.
Keep treatment times short || KBA4

Keep treatment times short

Sonalleve MR-HIFU can now suggest patient-specific cooling times between sonications to support treatment efficiency and reduce the likelihood of side effects. The technology behind this advance is Dual Mode Thermometry (DMT), an innovative fat tissue thermometry based on T2 data measuring cumulative heating over the whole treatment duration.

The right care, right away

Switch between diagnostic MR and HIFU therapy in minutes. HIFU is integrated in the dedicated Sonalleve table, which easily slides over the lowered MRI table. The diagnostic table is left in its lower position. Once prepared, you can perform a MR-HIFU procedure in three simple steps: planning on 3D MRI, treatment, and verification by contrast-enhanced MRI.
