Voluson Signature 20, Voluson Signature 18

The Voluson Signature 20 and Voluson Signature 18 are diagnostic ultrasound systems designed for comprehensive, multi-application imaging, with a particular focus on OB/GYN, utilizing a range of established and advanced ultrasound technologies including 3D/4D imaging, Doppler modalities, and Shearwave Elastography. These systems enhance clinical workflow through a mobile console, diverse transducer compatibility, numerous automated software features migrated from predicate devices, and new functionalities like voice command, ensuring broad diagnostic utility across various medical specialties.

The Voluson Signature 20 and Voluson Signature 18 are advanced diagnostic ultrasound systems designed for general-purpose medical imaging, with a specialization in obstetrics/gynecology (OB/GYN) applications, including real-time 3D/4D acquisition. These mobile console systems feature a user-friendly interface with a keyboard, touch panel, and high-resolution display, facilitating comprehensive image analysis, networking, and DICOM capabilities. They are intended for use by qualified healthcare professionals in hospital or clinic settings across a wide array of clinical applications, such as fetal/obstetrics, abdominal, pediatric, small organs (e.g., breast, testes, thyroid), cephalic (neonatal and adult), cardiac (adult and pediatric), peripheral vascular, musculoskeletal, transrectal, and transvaginal imaging. The systems employ established ultrasound technology, utilizing various transducers (linear, curved linear, matrix phased array) to support numerous imaging modes. These include B-mode, M-mode, Doppler (PW, CW, Color, Power, Tissue), HD-Flow, Harmonic Imaging, 3D/4D imaging, Elastography (including Shearwave), B-Flow, and Contrast imaging. Key differentiating features include migrated software functionalities from predicate devices such as Fetal Heart Support, SonoAVCfollicle, Shearwave Elastography, Perspective Rendering, SonoLyst, and Vscan Air CL Probe Support, alongside a new voice command feature. The device's design and safety are supported by extensive non-clinical testing, including evaluations for acoustic output, biocompatibility, and conformance to numerous medical device safety standards, ensuring its performance is comparable to legally marketed predicate devices.

• Q1. How does the performance of the new "Voice Command" feature compare to manual operation in terms of workflow efficiency and user satisfaction in diverse clinical settings (e.g., OB/GYN vs. cardiac)?; What are the specific quantitative improvements, if any, in image quality or diagnostic accuracy provided by the migrated software features (e.g., Shadow Reduction, FlowProfiles, Advanced STIC) compared to the predicate devices they originated from?; Could the integration of "Shearwave Elastography" across the Voluson Signature series expand its utility in applications beyond those previously established, such as early detection of specific fetal or gynecological conditions?; Considering the wide range of supported transducers and imaging modes, are there specific transducer-mode combinations where the Voluson Signature 20/18 demonstrates superior performance or offers unique diagnostic capabilities compared to the primary predicate (Voluson S series)?; What is the impact of the "Vscan Air CL Probe Support" on the system's portability and point-of-care usability, and are there any trade-offs in image quality or functionality when using this wireless probe compared to traditional cabled transducers?
