Area of Science:

Medical Imaging
Biomedical Engineering
Ultrasound Technology

Background:

Current angled ultrasound-guided punctures face challenges like longer procedure times and increased risks.
Vertical puncture techniques show promise but lack a clear understanding of needle tip detection principles.
Optimizing ultrasound probes for puncture requires a thorough understanding of needle tip detection.

Purpose of the Study:

To verify the principle of needle tip detection for vertical puncture.
To determine optimal measurement conditions for vertical puncture using ultrasound.
To investigate the factors affecting needle tip detection accuracy.

Main Methods:

Animal experiments utilizing a probe with a central puncture slit for needle tip detection.
Use of a puncture spacer for short-distance needle tip detection.
Investigation of needle tip signals using a ring probe, simulations, and experiments.
Analysis of ultrasound-guided wave leakage from the needle tip.

Main Results:

Confirmed the principle of needle tip detection using ultrasound-guided waves.
Verified the relationship between needle tip angle, detection intensity, and phase change.
Demonstrated that needle tip detection relies on the leakage of ultrasound-guided waves generated within the needle.

Conclusions:

The leakage of ultrasound-guided waves from the needle tip is the fundamental principle for its detection.
Understanding needle tip angle and insertion depth is crucial for optimizing detection.
This research provides a basis for improving ultrasound-guided vertical puncture techniques.
