Butterfly iQ3 Ultrasound System

The Butterfly iQ3 Ultrasound System is a portable diagnostic imaging device utilizing advanced capacitive micromachined ultrasonic transducer (CMUT) technology and mobile device integration to provide versatile, multi-mode ultrasound capabilities for a broad range of clinical applications in adult and pediatric patients. Its design focuses on enhancing point-of-care diagnostics through improved hardware components, including a next-generation CMUT array and new charging system, expanded imaging modes, and a user-friendly interface suitable for diverse healthcare settings.

The Butterfly iQ3 Ultrasound System is a portable, hand-held diagnostic imaging device designed for qualified healthcare professionals to visualize and measure anatomical structures and fluids in both adult and pediatric patients. It connects via USB to a standard commercial off-the-shelf (COTS) mobile device, utilizing a capacitive micromachined ultrasonic transducer (CMUT) array instead of traditional piezoelectric crystals, and is powered by a battery. The system features a touch screen user interface for controlling various imaging modes and viewing ultrasound imagery, with image interaction and capture managed through existing iOS and Android host applications. The iQ3 supports a wide range of clinical applications including Peripheral Vessel, Small Organs, Cardiac, Abdominal, Lung, Procedural Guidance, Urology, Fetal/Obstetric, Gynecological, Musculoskeletal, and Ophthalmic imaging. It offers multiple operating modes such as B-mode, B-mode + M-mode, B-mode + Color Doppler, B-mode + Power Doppler, Spectral Pulsed Wave Doppler, Fetal Heart Sounds, and newer modes like B-mode + Multi-Slice and B-mode + Sweep. Key technological updates from its predecessor include new printed circuit board assemblies, a next-generation CMUT array, a new custom battery, a butadiene synthetic rubber lens material, and a direct contact charging system, operating within an expanded frequency range of 1.0 - 12 MHz. Verification and validation testing confirmed the device meets its predetermined performance specifications.
