Understanding HIFU Technology
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.
A complete system, not just an amplifier: Our HIFU RF Power System integrates everything you need to drive your transducer: precision frequency generator, timing and gating circuits, high-power RF amplifier, comprehensive safety systems, and full digital control. Just connect your transducer and you're ready to go.
Simple USB control: No complex interfaces or proprietary software. Send simple ASCII text commands through a single USB port to control frequency, power, pulse timing, and all system functions. Works with any programming language or terminal program. Full documentation included.
Built-in safety: VSWR protection, over-temperature shutdown, arc detection, and hardware interlocks are all integrated. Focus on your application—the safety systems handle the rest.

Clinical & Research Applications
HIFU Applications
Our RF power generators support the full spectrum of focused ultrasound applications—from life-saving tumor ablation to cutting-edge research.
Oncology & Tumor Ablation
Non-invasive treatment of solid tumors in prostate, liver, breast, kidney, and bone. HIFU offers an alternative to surgery for patients who are not surgical candidates. The oncology segment represents 41% of the global HIFU market.
Neurology & Brain Therapy
MRI-guided focused ultrasound for essential tremor, Parkinson's disease tremor, and neuropathic pain. HIFU can create precise lesions in deep brain structures without opening the skull—a breakthrough alternative to invasive neurosurgery. Our MRI-compatible generators enable integration with MRgFUS platforms.
Aesthetic & Cosmetic
Non-invasive skin tightening, wrinkle reduction, and body contouring. Higher frequency HIFU (3-7 MHz) targets the SMAS layer and subcutaneous fat for cosmetic improvement without surgery. The aesthetic HIFU segment is the fastest-growing market, driven by consumer demand for minimally invasive treatments.
Research & Development
Flexible configurations for academic and industrial R&D. Develop new HIFU applications, validate treatment protocols, and characterize transducer performance. Our generators support the full research cycle from bench experiments to preclinical studies and regulatory submissions.
OEM System Integration
Designed for integration into commercial HIFU systems. Compact form factor, comprehensive API, and regulatory documentation support CE marking submissions. Volume pricing and design-in support for OEM partnerships.
Drug Delivery & Sonoporation
Low-intensity pulsed HIFU for enhanced drug delivery, blood-brain barrier opening, and sonodynamic therapy research. Precise pulse control enables investigation of bioeffects beyond thermal ablation.

Common Questions
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 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.
What is the warranty and support policy?
