Real-time aspiration-biopsy transducer

Area of Science:

• Medical imaging
• Interventional radiology
• Ultrasound technology

Background:

• Real-time imaging is crucial for accurate needle placement in aspiration-biopsy procedures.
• Monitoring needle trajectory and surrounding tissues improves procedural safety and efficacy.

Purpose of the Study:

• To evaluate the utility of a real-time aspiration-biopsy transducer for image-guided interventions.
• To assess the visualization capabilities of the transducer during needle insertion and target engagement.

Main Methods:

• In vitro and in vivo testing of a novel real-time aspiration-biopsy transducer.
• Utilizing ultrasound imaging to visualize needle path, tip, and adjacent anatomical structures.

Main Results:

• The transducer enables real-time monitoring of needle movement and adjacent organ motion.
• A distinct acoustic shadow reliably indicates optimal needle positioning within the skin.
• Consistent imaging of the needle tip is achieved in fluid-filled areas.
• While the needle path is observable, precise needle tip visualization presents challenges in certain contexts.

Conclusions:

• The real-time aspiration-biopsy transducer offers significant advantages in guiding needle placement during procedures.
• Improved visualization of needle trajectory and target structures enhances procedural precision.
• Further refinement may be needed for consistent needle tip visualization in all conditions.
