Sunor-R is a research-oriented tool for non-invasive deep brain neuromodulation. The field currently faces two major bottlenecks: first, accessing deep nuclei (e.g., via deep brain stimulation) is largely invasive; second, existing non-invasive ultrasound devices are mostly single- or dual-channel, lack transcranial aberration correction, and offer insufficient focusing accuracy to meet the demands of deep brain research. Centered on fully in-house developed phased-array technology and paired with transcranial correction algorithms, Sunor-R enables electronic and dynamic beam steering. It has passed type testing and animal studies, supporting a seamless transition from animal experiments to human research.
-
Research Flexibility — From cortex to deep nuclei, from a single nucleus to neural pathways. Whole-brain coverage with dynamically adjustable target number, size and position.
- 64-element phased array — Independent channel control, supporting electronic and dynamic focusing.
- Phased-array ultrasonic dynamic electronic focusing range — Axial ±30 cm, radial ±20 cm, covering deep brain nuclei.
- Customizable transducers — 16–256 elements available, frequency range 200 kHz–2 MHz, adaptable to diverse experimental requirements.
-
Millimeter-Level Precision — Transcranial correction algorithms keep the focus from shifting or spreading
- Focal spot size — 3 × 3 × 8 mm (at ~3 dB).
- Transcranial correction algorithm — 97.5% correction accuracy against the accepted clinical standard, completed within minutes on a single consumer-grade GPU.
-
Stability and Reliability — Fully in-house developed and validated through type testing and animal studies
- Fully in-house development — Proprietary phased-array transducers, multi-channel driving circuits and transcranial focusing algorithms, all under wholly independent IP; up to 1024-channel nanosecond-level synchronization (5 ns) guarantees consistency at the source.
- Safety validation — Ultrasound is non-invasive, reversible and non-destructive; safety has been verified through type testing, animal studies and skull experiments.
- Platform services — Beyond 64-channel-and-above precision targeting hardware, we offer animal study services, protocol design support and a target and functional connectivity data analysis platform, all connected to a global network of collaborating researchers.
