What We Do

Research Areas

End-to-end research — from algorithm design and simulation to real-time deployment on constrained hardware.

Ultrasound Systems

Custom hardware, transducer designs, front-end electronics, 3D-printed acoustic masks, and flexible array configurations for next-gen imaging.

Simulations & Modeling

Acoustic lens design, wave propagation simulations using k-Wave, and tissue-mimicking phantoms for rigorous experimental validation.

Ultrasound Software

Advanced beamforming, image reconstruction, neural network-based methods, 3D reconstruction, and aberration correction algorithms.

Clinical Applications

Lung ultrasound analysis, needle tracking, musculoskeletal imaging, sonomyography sensing, and super-resolution vascular imaging.

We work in signal, image & video processing, analytics and deploying them on edge devices — particularly for (ultra)sound imaging.
