Systems Algorithms and
Analytics for Imaging
and Beyond
Towards Cognitive Ultrasound – we work on making (ultra)sound affordable and intelligent, from algorithm design to deployment on edge devices.
Research Areas
End-to-end research – from algorithm design and simulation to real-time deployment on constrained hardware.
Transducers, acoustic masks, front-end electronics and simulation tools for ultrasound acquisition.
Beamforming, aberration correction, 3D and panoramic reconstruction, flow imaging and array processing, from simulation to real-time implementation.
Point-of-care applications in musculoskeletal, lung, interventional, prosthetic control and vascular imaging.
Interactive Demos
Browser-based demos of methods developed in our group. The computation runs on our server, and no installation is required.
A JAX based differentiable simulator and beamformer, where the speed of sound and the transmit and receive apodization are optimised by gradient descent on image quality metrics, e.g., gCNR. Scene presets (QA phantom, liver, breast) are available, and an uploaded image can also be used as the scene.
