Magnetically Guided Ultrasound

Innovative approaches to leverage ultrasound deep inside the human body in a minimally invasive way

OverviewApplications
Gastrointestinal diagnosticsMicro-ultrasound imagingEarly disease detectionGastrointestinal cancer

We pioneered using intelligent magnetic manipulation to obtain ultrasound images of anatomical features deep inside the human body. We demonstrated the feasibility of acquiring diagnostic-grade virtual biopsies in the gastrointestinal tract.

We are now focusing on multi-scale approaches, where a mini- or milli-scale magnetic ultrasound robot can deliver and activate micro-robots to cure deadly diseases like colorectal cancer.
