Medfield Diagnostics is a medical device company commercializing microwave technology for safer diagnostics in the health care business.

The microwave diagnostic technology can monitor changes and generate images of tissue in the human body. There are many areas where the technology can be valuable, from detecting bleedings and tumors to internal temperature measurements. Microwave diagnostic instruments can be compact compared to other diagnostic techniques, thus making it possible to implement them earlier in the healthcare chain, in emergency room and in ambulances enabling diagnosis in the acute phase.

Medfield's first product, Strokefinder R10, is an instrument for researchers within stroke and neurological research. It is versatile and can be used both for snapshot measurements to differentiate between ischemic (blood clot) and hemorrhagic stroke (bleeding in brain tissue) as well as to monitor changes over time.
