Focused Ultrasound Energy

What is High-Intensity Focused Ultrasound?

High-Intensity Focused Ultrasound (HIFU) is a non-invasive therapeutic technique that uses focused acoustic energy to precisely heat and ablate tissue deep within the body—without incisions or radiation.

How HIFU works: An RF power generator drives piezoelectric transducers that convert electrical energy into ultrasound waves. These waves are focused—like sunlight through a magnifying glass—to a precise focal point in the tissue, where temperatures can reach 60-85°C, causing coagulative necrosis of the target tissue while sparing surrounding structures.

The RF generator's role is critical: it must deliver stable, precisely controlled power at the exact frequency required by the transducer, with fast response times for real-time treatment control. Power output, frequency stability, and impedance matching directly impact treatment efficacy and safety.

Market growth: The global HIFU market reached $1.2 billion in 2024, driven by increasing adoption in oncology (41% market share), neurology, and aesthetics. Non-invasive alternatives to surgery are in high demand.

HIFU Generator FAQ

What is HIFU and how does it work?

High-Intensity Focused Ultrasound (HIFU) uses focused acoustic energy to heat and destroy targeted tissue non-invasively. An RF power generator drives piezoelectric transducers that convert electrical energy into ultrasound waves. These waves are focused to a precise point in the body—like sunlight through a magnifying glass—where temperatures reach 60-85°C, causing thermal ablation of the target tissue while sparing surrounding structures.

What frequency should I use for my HIFU application?

Frequency selection depends on treatment depth and target tissue. Lower frequencies (0.5-1 MHz) penetrate deeper (up to 15 cm) and are used for tumor ablation in liver, kidney, and prostate. Mid-range frequencies (1-3 MHz) are common for neurological HIFU and general therapeutic applications. Higher frequencies (3-7 MHz) provide precise, shallow penetration for aesthetic treatments targeting skin layers. Our team can help you select the optimal frequency for your specific application.

Is the generator compatible with MRI environments?

Yes. We offer MRI-compatible versions with EMI shielding and non-magnetic construction for MR-guided Focused Ultrasound (MRgFUS) applications. These generators can operate inside the MRI suite without interfering with imaging. The shielded version has been validated at 1.5T and 3T field strengths. Contact us to discuss your specific MRI integration requirements.

Can the generator drive phased array transducers?

Yes. We offer multi-channel configurations with up to 256 independently controlled channels for phased array transducers. Each channel provides individual amplitude and phase control for electronic beam steering and focal point adjustment. Multi-channel systems include synchronization features for coherent operation. Single-element and annular array transducers are also fully supported.

What safety features are included?

Safety is built into every generator: VSWR protection automatically reduces power if reflected power exceeds safe limits (prevents transducer damage). Over-temperature protection monitors internal temperatures and shuts down before overheating. Arc detection instantly cuts power if arcing is detected in the RF path. Hardware interlocks support external safety switches and emergency stops. Software limits allow you to define application-specific power and duration limits.

What regulatory documentation is available?

We provide comprehensive documentation to support your regulatory submissions: Design history file including specifications, test reports, and traceability. Risk analysis per ISO 14971. EMC test reports per IEC 60601-1-2. Electrical safety testing per IEC 60601-1. Certificates of conformance and calibration. Our regulatory affairs team can assist with FDA 510(k) and CE marking questions.

Do you support OEM integration and custom configurations?

Yes. We work closely with HIFU system developers on OEM projects: Custom frequencies matched to your transducer. Modified form factors for integration into your system enclosure. Custom interfaces and control protocols. Private labeling available. Volume pricing for production quantities. We can also provide design-in support, prototypes, and engineering samples for evaluation.
