Vivid E80, Vivid E90, Vivid E95

The Vivid E80/E90/E95 systems are advanced, general-purpose diagnostic ultrasound platforms, specialized for cardiac imaging, that utilize a comprehensive suite of imaging modes, transducers, and digital processing capabilities for detailed anatomical and physiological assessment. These systems incorporate innovative software enhancements, including AI-driven analysis tools for automated measurements like ejection fraction and strain, CT fusion for procedural guidance, and advanced image optimization techniques, to improve diagnostic accuracy and workflow efficiency across a broad spectrum of clinical applications.

The Vivid E80, Vivid E90, and Vivid E95 are sophisticated, general-purpose diagnostic ultrasound systems primarily designed for comprehensive cardiac imaging, but also supporting a wide array of other clinical applications including obstetrics, abdominal, vascular, and musculoskeletal imaging. Operated by qualified physicians, these systems facilitate ultrasound imaging, measurement, display, and analysis of the human body and fluids. They feature a mobile console with advanced display and control interfaces, support a diverse range of electronic array transducers including those for real-time 3D/4D and transesophageal imaging, and are equipped for digital acquisition, processing, analysis, and network integration. Employing established ultrasound principles, these systems offer numerous imaging modes such as B-mode, M-mode, various Doppler modalities (PW, CW, Color), 3D/4D imaging, harmonic imaging, and coded pulse. Recent technological advancements include the integration of AI-driven tools like "Easy Auto EF" and "Easy AFI LV," which provide automated cardiac function measurements with high accuracy (dice scores exceeding 91-92% in testing across diverse datasets). Other significant software enhancements comprise "cSoundTM Adapt" for improved contrast, "CT Fusion Live" for real-time overlay of CT data, "Strain Elastography" for tissue stiffness assessment, and various workflow optimization tools, all aimed at enhancing diagnostic capabilities and clinical efficiency.
