Medfield Diagnostics AB is a Sweden-based developer of medical instrumentation. The Company develops, markets and sells diagnostic instrumentation based on microwave technology. The Company's microwave technology complements other imaging principles in two main ways. Firstly microwaves sense dielectric properties and provide high contrast for biological matter with different water content, thus enabling diagnosis of for example blood in brain tissue or tumors in breast tissue. Secondly microwave instruments are compact and thus used earlier in the healthcare chain, in emergency rooms and in ambulances. The Company’s products include R10; the M100, available on stroke services for night-time surveillance of patients at increased risk of stroke, as well as D1000 that is a diagnostic instrument for use in emergency rooms and ambulances to diagnose the type of stroke, ischemic (blood clot) or hemorrhagic (bleeding).
