Voluson SWIFT; Voluson SWIFT+

The Voluson SWIFT and SWIFT+ are advanced diagnostic ultrasound systems focused on OB/GYN applications with real-time 3D/4D imaging, employing a range of imaging modes and transducer technologies. These systems integrate new software features, including AI-powered tools like Auto-Caliper for follicular assessment, to improve image quality, diagnostic capabilities, and workflow efficiency in clinical practice.

The Voluson SWIFT and Voluson SWIFT+ are general-purpose diagnostic ultrasound systems primarily designed for qualified healthcare professionals to perform ultrasound imaging, measurement, display, and analysis of the human body and fluids. These systems are specialized for obstetrics and gynecology (OB/GYN) applications, featuring real-time 3D/4D acquisition capabilities, and are built on a mobile console with a full touch monitor, digital acquisition, processing, display, networking, and DICOM functionalities. They support a variety of transducers, including linear, curved linear, and matrix phased array types, for a wide range of clinical applications such as fetal/obstetrics, abdominal, pediatric, small organs, cephalic (neonatal and adult), cardiac, peripheral vascular, musculoskeletal, transrectal, and transvaginal imaging. The systems incorporate numerous imaging modes, including B-mode, M-mode, Anatomical M-Mode, Pulsed Wave (PW) and Continuous Wave (CW) Doppler, Color Doppler, Power Doppler, HD-Flow, Harmonic Imaging, 3D/4D imaging, Elastography, and B-Flow. Significant software enhancements include features such as Shadow Reduction, Autolive, RadiantFlow, Volume with color, Spine Trace, Fractional Limb Volume, Timer for Biophysical Profile (BPP), Fetal Heart Support, SonoPelvic Floor, an AI-driven Auto-Caliper tool, Reminders, and software download capabilities. The Auto-Caliper feature, specifically for 2D caliper placement on follicles, was developed using AI trained on 223 datasets and verified on 67 volumes, demonstrating a success rate of 70% or higher when evaluated by clinical experts comparing AI-generated placements to manual measurements.

• Q1. What is the specific clinical impact of the "Auto-Caliper" AI feature on workflow efficiency and measurement consistency in follicular assessment compared to manual methods?; How does the "RadiantFlow" feature quantitatively improve the visualization and assessment of low-velocity blood flow in complex fetal or gynecological vascular structures over traditional Color Doppler?; What are the performance metrics of the "Spine Trace" and "Fractional Limb Volume" tools across varying fetal gestational ages and in the presence of common imaging artifacts?; Can the "SonoPelvic Floor" feature provide standardized, reproducible measurements for pelvic floor muscle assessment, and how does its diagnostic accuracy compare to existing clinical evaluation methods?; Beyond the 70% success rate for follicle identification, what is the measurement accuracy (e.g., mean absolute difference, Bland-Altman analysis) of the "Auto-Caliper" feature compared to expert sonographer measurements?
