GE 8L-RS Linear Array Transducer Ultrasound Crystal Ultrasound Scanhead

Product Description

GE 8L-RS Linear Array Transducer Ultrasound Crystal Ultrasound Scanhead

Ultrasound Probe Array / Crystal / Scanhead / Acoustic Moudle / Transducer Overview

1. Material Composition
The active element is typically made of piezoelectric crystalsor newer materials like for higher sensitivity and bandwidth.  
The lens or matching layer is often composed of acoustic polymers to optimize impedance matching between the transducer and tissue.  

2. Frequency Range
Operates at specific frequencies, with higher frequencies offering better resolution but shallower penetration.  
Multi-frequency probes support adjustable frequencies for different imaging depths.  

3. Array Configuration 
Linear array: Flat footprint, high near-field resolution (e.g., vascular imaging).  
Curved array (convex): Wider field of view for deep abdominal scans.  
Phased array: Small footprint with steering capability (e.g., cardiac imaging).  

4. Aperture Size & Footprint
The physical size and shape vary by application (e.g., small footprints for interventional or pediatric use).  

5. Damping Layer
A backing layer absorbs backward-directed vibrations to shorten pulse duration, improving axial resolution.  

6. Matching Layer 
Reduces acoustic impedance mismatch between the transducer and tissue, enhancing energy transmission.  

7. Thermal & Electrical Safety
Designed to minimize heat generation (meeting FDA/IEC limits for surface temperature rise).  
Electrically insulated to protect patients and operators.  

8. Beamforming Capability 
Modern probes support dynamic focusing, electronic steering, and multi-line acquisition for real-time imaging.  

9. Durability & Sterilization 
Encased in robust materials (e.g., plastic, metal) resistant to wear and chemical disinfectants.  
Some probes are waterproof for intraoperative or endoscopic use.  

10. Specialized Variants
3D/4D probes: Incorporate mechanical or matrix arrays for volumetric imaging.  
Intracavitary probes: Miniaturized designs for transvaginal/transrectal applications.
