GE 3Sc-RS Phased Array Ultrasound Probe

The GE 3Sc-RS is a wideband, sector phased-array ultrasound transducer designed for deep-cavity hemodynamic assessment, cardiac evaluations, abdominal screening, and transcranial Doppler analysis. Engineered with high-efficiency acoustic impedance matching and piezoelectric crystal arrays, the 3Sc-RS operates over a broad nominal bandwidth of 1.3 MHz to 4.0 MHz.

Configured with GE’s proprietary zero-insertion-force RS connector (paddle-style multi-pin terminal), this probe interfaces across GE console lines—including the Vivid, LOGIQ, Voluson, Versana, and Venue series. Beyond hospital cardiology units, the 3Sc-RS is widely deployed in point-of-care ultrasound (POCUS) configurations aboard maritime research vessels, naval hospital ships, offshore platform medical bays, and heavy commercial fleet infirmaries where compact, high-reliability diagnostic instruments are required under harsh vibration and variable thermal conditions.

Technical Specifications

Frequently Asked Questions

What is the primary difference between the 3Sc-RS and the older 3S-RS probe?

The 3Sc-RS represents GE’s single-crystal-inspired acoustic architecture upgrade over the legacy 3S-RS. It provides broader acoustic bandwidth, improved penetration in high-BMI patients, enhanced signal-to-noise ratio, and noticeably cleaner endocardial border delineation in difficult echocardiographic windows.

Can I plug the GE 3Sc-RS into a console with standard rectangular D-connectors?

No. The 3Sc-RS features a compact, flat multi-pin RS connector designed for portable and mid-range GE consoles. Systems utilizing full-sized rectangular “D-connectors” (such as the high-end Vivid E9 or LOGIQ E9) require an active RS-to-D mechanical port adapter, or the native D-series probe equivalent (e.g., M5S-D).

How do I verify if my GE Vivid or LOGIQ software version supports this probe?

Most modern LOGIQ and Vivid series running system software revision R2 or later support the 3Sc-RS natively. Navigate to your system’s Utility > System Diagnostics > System Info page to verify installed software options and transducer software keys.

What are the symptoms of acoustic lens delamination?

Delamination occurs when the protective front-face rubber membrane separates from the internal matching layer. Visible signs include air bubbles under the lens face, peeling around the perimeter seams, or acoustic shadow lines along the near-field image sector. If delamination is present, discontinue use immediately to prevent gel ingress into the piezo array and avoid electrical leakage risks.

What test documentation accompanies reconditioned probes?

Every reconditioned GE 3Sc-RS unit is accompanied by a certified bench test report detailing channel capacitance, electrical safety/leakage current measurements in compliance with IEC 60601-1, and an acoustic phantom profile confirming beam symmetry and penetration depth.
