MicrUs EXT-1H


MicrUs is a new generation of a USB-powered pocket-size point of care ultrasound imaging system. It offers ultrasound screening in B, M, B/M, 4B modes together with Speckle Reduction Processing, Trapezoid and Spatial compound imaging. Various transducers can be connected and disconnected in second thanks to advanced probe recognition technology. MicrUs is a fanless device so it’s well suited for ultrasound-guided procedures. Ultrasound scanner can be fully controlled from a remote computer providing possibilities for telemedicine and educational purposes. Software Development Kit available to scientific organizations and industry enables advanced manipulation with the ultrasound data and customization of the user interface.
