Vivid T8, Vivid T9

The Vivid T8/Vivid T9 is an advanced, mobile diagnostic ultrasound system primarily focused on cardiac imaging, employing a variety of transducers and imaging modes to provide comprehensive diagnostic capabilities across numerous clinical applications. It integrates artificial intelligence for automated measurements and enhanced image analysis, alongside features like Scan Coach and Stream Server to improve workflow efficiency and support remote collaboration.

The Vivid T8/Vivid T9 is a general-purpose diagnostic ultrasound system, with a specialization in cardiac imaging, intended for use by qualified healthcare professionals. It facilitates ultrasound imaging, measurement, display, and analysis of the human body and fluid across a wide array of clinical applications including Fetal/Obstetrics, Abdominal, Pediatric, Small Organ, Cephalic (Neonatal and Adult), Cardiac, Peripheral Vascular, Musculoskeletal, Transcranial, Transesophageal, Transrectal, Transvaginal, interventional guidance, and intraoperative vascular procedures. The system employs various electronic array transducers (linear, curved, sector/phased, matrix, dual array, and dedicated CW) and supports multiple operating modes such as B-mode, M-mode, PW Doppler, CW Doppler, Color Doppler, Color M-mode, Power Doppler, Harmonic Imaging, Coded Pulse, and combined modes. The Vivid T8/Vivid T9 system is a mobile console featuring a control panel, color LCD touch panel, LCD display monitor, and options for image storage and printing. It incorporates advanced features like AI Auto Measure – 2D for semi-automated cardiac measurements on PLAX images, AI Auto Measure – Spectrum Recognition for automated Doppler spectra recognition and measurement initiation, AFI 3.0 for left ventricle analysis from GEHC raw data and third-party DICOM images, and Auto EF 3.0 for LV function assessment under similar conditions. Additional functionalities include AFI RV for right ventricular strain analysis, AFI LA for left atrial strain and volume measurements, Scan Coach for image acquisition guidance, and Stream Server for remote viewing and consultation. Hardware enhancements include a new CPU, a new LCD monitor, an HDMI port, and an upgrade from USB2.0 to USB3.1.
