SonoScape P20 Trolley Color Doppler Ultrasound System

The SonoScape P20 is a trolley-based color Doppler ultrasound system engineered for daily clinical practice across general imaging, obstetrics, gynecology, and cardiovascular applications. It combines single-crystal and composite-crystal transducer technologies, C-xlasto quantitative elastography, contrast-enhanced imaging with 8 TIC curves, and 4D diagnostic capabilities in a mobile console with a touchscreen and intuitive interface—designed to deliver reliable diagnostic confidence without compromising value across shared-service clinical environments.

The P20 Series received FDA 510(k) clearance under K172993 (December 5, 2017) as a Class II ultrasonic pulsed Doppler imaging system (Product Code IYN, 21 CFR 892.1550), following a Traditional review. A subsequent clearance under K221140 (September 13, 2022) covers the P20 Elite Series, which includes the P20 Elite, P20 Exp, P25 Exp, P22 Elite/Exp, P15 Elite/Exp, and P25 Elite. The P20 base designation falls within the broader P20 Series family; the FDA summary for K172993 states “No clinical data was required”, with substantial equivalence demonstrated through bench testing including electrical, mechanical, thermal, and electromagnetic compatibility safety, biocompatibility, and acoustic output measurements conforming to IEC 60601 series, ISO 10993, and AIUM/NEMA UD 2/3. No independent peer-reviewed clinical validation study specific to the P20 was identified in the public literature during preparation of this page.

The imaging chain is anchored by single-crystal C1-5 for abdominal and obstetric imaging and single-crystal S1-5 for cardiology and transcranial applications, alongside composite-crystal linear 12L-A, 12L-B, and 9L-A covering an ultra-wide frequency bandwidth with virtually no blind spots across vascular, breast, thyroid, and musculoskeletal scanning. The system supports B (including Tissue Harmonic Imaging), M, Anatomical M, Color Doppler, Color M, Power Doppler, Directional Power Doppler, PW Doppler, CW Doppler, TDI, Elastography, Contrast Imaging, and 3D/4D imaging, with a probe frequency range of 1.0–25.0 MHz. Four active probe ports plus one additional port support efficient probe management, and the configuration includes a 21.5-inch LED monitor and a 13.3-inch touchscreen for intuitive operation.

Key Features & Benefits

Single-Crystal C1-5 and S1-5 Transducers for Abdominal, Obstetric, and Cardiac Imaging

The single-crystal C1-5 and S1-5 transducers increase crystal alignment uniformity and energy transmission efficiency, delivering superior sensitivity and resolution in both near and far fields for abdominal, obstetric, cardiac, and transcranial applications. The composite-crystal linear 12L-A, 12L-B, and 9L-A achieve a better acoustic spectrum and lower acoustic impedance through reformed piezoelectric materials, covering an ultra-wide frequency bandwidth with nearly no blind spot for vascular, breast, thyroid, and musculoskeletal scanning.

C-xlasto Quantitative Elastography

C-xlasto Imaging enables comprehensive quantitative elastic analysis, rapidly calculating Strain Ratio and displaying unusually hard or soft anomalies within soft tissue. The system is supported by linear, convex, and transvaginal probes to ensure good reproducibility and highly consistent quantitative elastic results—extending the platform into strain elastography for lesion assessment.

Contrast Imaging with 8 TIC Curves

Contrast Imaging uses contrast agents to provide enhanced visualization of difficult-to-view blood flow, with 8 TIC (Time-Intensity Curve) curves allowing clinicians to assess perfusion dynamics across a wide range of clinical settings, including lesion location and evaluation. This supports contrast-enhanced assessment of tissue perfusion within the clinician's workflow.

4D Obstetric and Gynecologic Tools: S-Live, Pelvic Floor 4D, Auto NT, Auto Face, and AVC Follicle

The P20 is equipped with diagnostic 4D technology positioned for extraordinary performance in obstetrics and gynecology. S-Live allows detailed visualization of subtle anatomical features with real-time 3D images, supporting intuitive diagnosis and patient communication. Pelvic Floor 4D provides transperineal assessment of vaginal delivery impact on the female anterior compartment, supporting evaluation of pelvic organ prolapse and muscle integrity. Auto NT automates nuchal translucency thickness measurement, Auto Face removes masking layers in front of the fetal face, and AVC Follicle supports automated follicle assessment.

Cardiac Tools: TDI, Anatomic M, Auto EF, and Auto IMT

Tissue Doppler Imaging (TDI) provides velocities and clinical information on myocardial functions, supporting analysis and comparison of different parts of the heart. Anatomic M Mode allows free placement of sample lines to observe myocardial motion at different phases and accurately measure myocardial thickness and heart size in difficult patients. Auto EF supports automatic ejection fraction calculation, and Auto IMT provides one-click measurement of carotid intima-media thickness for cardiovascular risk assessment.

Mobile Console with 21.5-Inch LED Monitor and 5 Probe Ports

The P20 is a mobile, software-controlled color diagnostic ultrasound system with a mobile console, touchscreen/keyboard control panel, and color LCD monitor. The configuration includes a 21.5-inch LED display and a 13.3-inch touchscreen, alongside 5 probe connectors (4 active and interchangeable, 1 inactive) for efficient multi-specialty workflow. The system dimensions are 518 × 751 × 1110–1680 mm with a weight of approximately 86 kg.

Broad Clinical Applications

The FDA-cleared indications for the P20 Series cover Fetal, Abdominal, Pediatric, Small Organ (breast, testes, thyroid), Cephalic (neonatal and adult), Trans-rectal, Trans-vaginal, Peripheral Vascular, Muscular, Musculo-skeletal (Conventional and Superficial), Cardiac (pediatric and adult), Trans-esophageal (Cardiac), Laparoscopic, OB/GYN, and Urology applications, with age, weight, health condition, and race unlimited.
