Background:

External tracking systems for laparoscopic surgery are costly and cumbersome.
Existing laparoscopic ultrasound (LUS) probe tracking systems often use fiducial markers with limitations in speed and robustness.
There is a need for improved vision-based tracking solutions in LUS.

Purpose of the Study:

To develop a novel binary dot array marker for robust and fast vision-based tracking of LUS probes.
To overcome the limitations of existing fiducial markers in laparoscopic surgery.
To enhance the accuracy and efficiency of ultrasound-guided laparoscopic procedures.

Main Methods:

Proposed a novel binary dot array marker with two distinct colored dots (green and blue).
Designed the marker to form unique identification dot subarrays for robust detection.
Implemented a vision-based tracking system utilizing the binary dot array marker for LUS probe localization.

Main Results:

The binary dot array marker demonstrated superior robustness against occlusions compared to traditional fiducial markers.
The proposed system achieved better computational efficiency and tracking accuracy.
Evaluation confirmed the marker's effectiveness in real-world laparoscopic surgery scenarios.

Conclusions:

The novel binary dot array marker provides a robust, efficient, and accurate solution for laparoscopic ultrasound probe tracking.
This technology can potentially replace current external tracking systems, reducing costs and complexity in surgeries.
The system's performance suggests significant advancements in vision-based surgical guidance.
