The HandScan measures blood flow in joints, in the hands and the wrists by means of diffuse optical transmission in combination with blood flow modulation. Optical technology makes the system safe for the patient and quick and inexpensive to use – one session takes just 2.5 minutes.

Hemics markets the HandScan as a compact, user-friendly and affordable device. It is responsible for the data algorithm, which translates the measurement data from the scanner into clinical information for the rheumatologist. Demcon is responsible for the systems engineering, electronics, mechanics, optics and embedded software. In addition to the illumination module, an intuitive user interface and industrial design require special attention, with a view to the acceptance of the device in the daily practice of the rheumatologist.
