GE 9T-RS
The 9T-RS is a transesophageal echocardiography probe with a 7.5 x 10.7 mm distal tip and 37.5 mm insertion length, sized for both pediatric and smaller adult patients. The 4.0 – 10.0 MHz bandwidth delivers near-field valve detail at high frequency while maintaining penetration for posterior cardiac structures at 3 MHz. Multi-plane rotation provides continuous imaging from 0 to 180 degrees for full structural assessment on the Vivid IQ, Vivid T9, and Vivid S70 platforms.

Specifications
Wide bandwidth balances near-field valve detail at high frequency with posterior cardiac penetration at low frequency.
Compact tip allows esophageal passage in pediatric patients and smaller adults.
Short insertion length designed for pediatric and smaller adult esophageal anatomy.
Standard cardiac sector captures complete four-chamber and valve views from the esophageal position.
Sufficient penetration for transgastric views of the full left ventricle.
Continuous rotation provides all standard TEE views without repositioning the probe.
Complete cardiac mode set for structural and hemodynamic assessment during TEE.
RS-Pin interface connects to GE Vivid cardiovascular ultrasound systems.
Applications
Transesophageal Echocardiography
Multi-plane imaging from 0 to 180 degrees provides standard TEE views including mid-esophageal four-chamber, two-chamber, long-axis, and transgastric short-axis. The 10 MHz upper range resolves valve leaflet morphology, vegetations, and thrombus with detail not achievable from transthoracic windows. The 7.5 x 10.7 mm tip eases passage in pediatric patients and adults with smaller esophageal anatomy.
Intraoperative Cardiac Monitoring
Real-time TEE during cardiac and non-cardiac surgery monitors ventricular function, volume status, and valve competence. The 3 MHz low end penetrates to 14 cm for complete visualization of the left ventricle from the transgastric window. Color Doppler detects new or worsening valvular regurgitation immediately after surgical repair, guiding intraoperative decision-making.
Pediatric TEE Assessment
The compact 7.5 x 10.7 mm tip and 37.5 mm shaft length are designed for passage in pediatric patients undergoing congenital heart surgery or catheter-based interventions. High-frequency imaging at 8–10 MHz resolves small intracardiac structures including atrial and ventricular septal defects, patent ductus arteriosus, and valve anatomy. Multi-plane rotation maps shunt pathways and guides catheter positioning during interventional procedures.
