SonoScape P20 Elite Trolley Color Doppler Ultrasound System

The SonoScape P20 Elite is a trolley-based color Doppler ultrasound system engineered for general imaging and women's health, combining single-crystal and composite-crystal transducer technologies, μ-Scan+ and SR Flow image processing, and AI-assisted clinical tools in a compact, battery-backed enclosure designed for space-constrained clinical environments and multi-room mobility.

The P20 Elite Series received FDA 510(k) clearance under K221140 (September 13, 2022) as a Class II ultrasonic pulsed Doppler imaging system (Product Code IYN, 21 CFR 892.1550), following a 147-day traditional 510(k) review. The clearance covers the P20 Elite Series Digital Color Doppler Ultrasound System, which includes the P20 Elite, P20 Exp, P15 Elite, P15 Exp, P22 Elite, P22 Exp, and P25 Exp models according to FDA establishment listing records. The FDA summary states “No clinical testing was required. Bench testing only” , including electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), acoustic output (IEC 60601-2-37, AIUM/NEMA UD 2), software verification/validation (IEC 62304), and biocompatibility testing per ISO 10993-5 and ISO 10993-10. No independent peer-reviewed clinical validation study specific to the P20 Elite 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 patients and single-crystal S1-5 for cardiology and transcranial applications, alongside composite-crystal linear transducers 12L-A, 12L-B, and 9L-A covering an ultra-wide frequency bandwidth with nearly no blind spot across vascular, breast, thyroid, and MSK scanning. The system includes μ-Scan+ for noise reduction and boundary continuity, SR Flow for low-velocity flow detection, C-xlasto Imaging for quantitative strain ratio analysis, Bright Flow for 3D-like color Doppler without a volume transducer, Contrast Imaging for enhanced flow visualization, and Auto IMT for carotid intima-media thickness measurement.

Key Features & Benefits

Single-Crystal C1-5 and S1-5 Transducers

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 across vascular, breast, thyroid, and MSK scanning.

μ-Scan+ and SR Flow for Image Clarity and Hemodynamic Accuracy

μ-Scan+ reduces noise, improves image uniformity, and enhances boundary continuity for true-to-life detail and improved visualization. SR Flow improves low-velocity flow signal detection, enhances spatial resolution, and overcomes flow overflow to present real hemodynamic information.

AI-Assisted Clinical Tools: Auto OB, Auto NT, Auto EF, Auto Bladder, Auto IMT

The P20 Elite integrates automated measurement and analysis tools designed to support efficient workflow and objective assessment. The FDA 510(k) summary lists Auto OB, Auto NT, Auto EF, Auto Bladder, and Auto IMT as included automated measurement/analysis functions, alongside S-MSK, Sono-Help, Sono-Assistant, and Sono-Synch assistant functions. Auto IMT provides one-click measurement of anterior and posterior intima-media thickness of the common carotid for cardiovascular risk assessment. AVC Follicle supports volume-data-based automatic follicular calculation for reproductive health assessment. These are measurement and workflow aids; clinical interpretation remains with the qualified user.

C-xlasto Imaging and Contrast Imaging

C-xlasto Imaging enables comprehensive quantitative elastic analysis, rapidly calculating Strain Ratio and displaying unusually hard or soft anomalies within soft tissue, supported by multiple probes for good reproducibility and consistent quantitative elastic results. Contrast Imaging uses contrast agents that provide loud signal reflection, giving a more enhanced image of difficult-to-view blood flow while controlling acoustic pressure and providing promising image quality with a smaller agent dose.

Bright Flow and S-Live Silhouette

Bright Flow provides 3D-like color Doppler flow without requiring a volume transducer, strengthening boundary definition of vessel walls and supporting more intuitive visualization of blood flow structures with less artifact—helpful for tiny vessels and crossing vessels. S-Live Silhouette applies a virtual light source and shadowing effect to see through the surface and clearly delineate the outlines of bone, organs, cavities, vessel walls, and other internal structures, supporting anatomical identification and complex malformation evaluation.

Compact Design with 4 Active Ports, Dual Battery, and 23.8-Inch LED Display

The P20 Elite features a compact and lightweight design for space-constrained environments, with 4 active transducer ports plus 1 dedicated storage port and an endocavity transducer holder for organized workflow. Two integrated batteries provide extended operating time for mobile examinations and intra-facility transport. The 23.8-inch LED display (optional) delivers excellent contrast resolution and image clarity for better visualization and more diagnostic information, and the high-sensitivity touchscreen adjusts to user viewing preference in any scanning environment.

Broad Clinical Applications

The FDA-cleared indications cover Fetal, Abdominal, Pediatric, Small Organ (breast, testes, thyroid), Cephalic (neonatal and adult), Trans-rectal, Trans-vaginal, Peripheral Vascular, Cerebral Vascular, Musculoskeletal (conventional and superficial), Cardiac (pediatric and adult), Trans-esophageal (cardiac), Laparoscopic, OB/GYN, and Urology applications, with age, weight, health condition, and race unlimited. Modes of operation include B, M, PW Doppler, CW Doppler, Color Doppler, Color M Doppler, Power Doppler, Directional Power Doppler, Tissue Harmonic Imaging, Tissue Doppler Imaging, 3D/4D, Elastography, Contrast, and combined modes.
