GE Healthcare 5131945 Probe Type 7S-RS

The GE HealthCare 7S-RS, part number 5131945, is a compact wideband phased-array ultrasound transducer engineered for high-resolution pediatric cardiac and neonatal imaging on compatible GE ultrasound systems.

Operating across a 3.5–8.0 MHz frequency range, the 7S-RS delivers the balance of penetration and detailed visualization required for smaller patients and challenging acoustic windows. Its compact 17 × 24 mm footprint allows precise probe positioning, while the 90° sector field of view provides broad visualization of cardiac and anatomical structures from a relatively small acoustic window.

Purpose-Built for Pediatric Cardiac Imaging

The 7S-RS combines a small transducer footprint with the broad sector image produced by phased-array technology, making it especially effective when access between ribs or through other restricted acoustic windows is required.

Its higher-frequency operating range provides the image resolution needed for smaller anatomical structures while retaining sufficient penetration for pediatric cardiac examinations. The probe is also designed to support neonatal cephalic imaging, where detailed visualization and precise probe placement are particularly important.

On supported GE platforms, the 7S-RS can be used with advanced imaging modes including 2D imaging, harmonic imaging, M-Mode, Color Doppler, Pulsed-Wave Doppler, and Continuous-Wave Doppler, providing a versatile solution for cardiovascular ultrasound workflows.

The GE HealthCare 7S-RS is an excellent replacement or supplemental transducer for facilities maintaining compatible GE cardiovascular ultrasound systems and requiring a dedicated probe for pediatric and neonatal imaging.

Compatibility should be verified using the probe model, part number, ultrasound system model, software revision, and system configuration before purchase.
