Effective treatment of stroke requires rapid diagnosis using brain imaging followed by rapid optimal treatment. Existing imaging using MRI or x-ray CT are typically too slow in practice since they first require the transport of stroke victims to large central facilities.
Ultrasound imaging is readily portable, fast and universally applicable, but current technology cannot generate accurate images of the adult brain within the skull. Using a technique borrowed from geophysics, full-waveform inversion, it appears possible to image the brain at high resolution through the skull using transmitted ultrasound.
This technology is especially relevant to stroke where it has the potential to save many thousands of lives and significantly reduce stroke-related disability.
