V8 Diagnostic Ultrasound System, V7 Diagnostic Ultrasound System

The V8 and V7 Diagnostic Ultrasound Systems are designed to provide comprehensive, multi-modal ultrasound imaging and body fluid analysis for a wide range of clinical applications, operated by qualified healthcare professionals. These systems utilize advanced software control and incorporate AI-enhanced features, such as the NerveTrack for improved nerve identification, and offer new transducer options to enhance diagnostic versatility and performance.

The V8 and V7 Diagnostic Ultrasound Systems are general-purpose, mobile, software-controlled devices designed for acquiring ultrasound images and analyzing body fluids to aid in clinical diagnosis by trained healthcare professionals. These systems support a comprehensive range of clinical applications, including fetal/obstetrics, abdominal, gynecological, cardiac, musculoskeletal, and peripheral vessel imaging, among others. They offer multiple modes of operation such as 2D, Color Doppler, Power Doppler, M-mode, Pulsed Wave and Continuous Wave Doppler, Tissue Doppler Imaging, ElastoScan, and 3D/4D imaging, providing versatile diagnostic capabilities for use in hospitals, private practices, and clinics. The V8/V7 systems build upon existing ultrasound technology, with notable enhancements including an expanded AI-based NerveTrack feature in the V8 model for detecting specific nerve types in the elbow (Median, Ulnar, Radial nerves) and neck/shoulder (Infraclavicular, Supraclavicular, Axillary Brachial Plexus). This AI feature was validated for accuracy (average 91.7%) and speed (average 7.93 FPS) using a dataset of 2,146 images from 18 Korean subjects, demonstrating good generalizability across BMI subgroups. The V7 system introduces three new transducers (CA1-7SD, EA2-11ARD, EA2-11AVD) and incorporates a migrated transducer (CV1-8AD), all of which have undergone biocompatibility and image performance testing. Both systems maintain capabilities for anatomical measurements, real-time acoustic output display (Mechanical Index and Thermal Index), image capture, review, and reporting.

• Q1. How does the NerveTrack AI algorithm differentiate between the specific nerve types (MN, UN, RN, ISBP, SCBP, AxBP), and what are its performance metrics for each individual nerve type, especially in varying patient anatomies or pathological conditions?; Given that the NerveTrack AI validation dataset consisted entirely of Korean subjects, what studies are planned or would be recommended to assess its performance and generalizability across more diverse ethnic populations and varied BMI distributions?; What are the specific image quality improvements or quantitative performance benefits (e.g., resolution, penetration, contrast) offered by the new transducers (CA1-7SD, EA2-11ARD, EA2-11AVD) and the migrated transducer (CV1-8AD) on the V7 system compared to previous or alternative transducers?; Beyond the listed accuracy and speed for NerveTrack, what is the sensitivity and specificity of the AI for detecting nerves, particularly in challenging cases with subtle anatomical variations or overlying structures?; How does the ElastoScan mode on the V8/V7 systems quantitatively assess tissue stiffness, and what validation has been performed to correlate its findings with established diagnostic methods across its intended clinical applications?
