Clarius Ultrasound System

The Clarius Ultrasound Scanner is a portable, wireless diagnostic ultrasound system designed for real-time, multi-modal imaging and fluid flow analysis across a wide range of clinical applications. It operates by transmitting ultrasound waves via various transducers, processing the echo data, and displaying images on standard mobile devices, aiming to provide accessible and versatile diagnostic capabilities to trained healthcare professionals.

The Clarius Ultrasound Scanner is a portable, software-controlled diagnostic ultrasound system designed for acquiring and displaying high-resolution, real-time ultrasound images and performing fluid flow analysis. Its methodology involves wireless transducers (C3 Convex, C7 Convex, L7 Linear) that operate on the scientific principle of piezoelectricity, where materials within the transducer transmit high-frequency, non-ionizing sound waves into the body and convert the subsequent detected echoes into electronic signals. These signals are processed to construct an image, which is then wirelessly transmitted via Wi-Fi Direct to a commercial off-the-shelf iOS or Android device for display using the Clarius App. The system supports multiple imaging modes, including B-mode, M-mode, Color Doppler, Power Doppler, and combined modes (B+M, B+Color Doppler, B+Power Doppler), and is intended for use by trained healthcare professionals across various environments, including emergency medical services. This iteration of the Clarius Ultrasound System expands upon previous versions by incorporating M-mode, color doppler, power doppler, and combined modes for the C3 and L7 scanners, and introduces the new C7 scanner with these capabilities. It broadens clinical applications to include intraoperative (abdominal organs & vascular) use for all scanners, cardiac (adult and pediatric) for the C3 scanner, and ophthalmic for the L7 scanner. A new C3-L clip-on accessory enhances the C3 scanner's versatility. The system is IP67 rated for dust and water resistance and compliant with standards for emergency medical service environments, offering a robust solution for diverse diagnostic needs such as ophthalmic, fetal, abdominal, pediatric, small organ, cephalic, musculoskeletal, urological, gynecological, cardiac, and vascular imaging, as well as procedural guidance of needles.
