Abstract: This letter presents a novel, integrated multimodal data acquisition system for simultaneously capturing the six degrees of freedom motion data and real-time visual information, designed primarily for ultrasound imaging applications. The system combines inertial measurement units, ArUco markers, and a video capture device to achieve high-accuracy motion tracking synchronized with real-time ultrasound imaging. Our approach provides a cost-effective and portable setup that is capable of recording accurate translational and rotational data. The experimental results demonstrate promising results with $1.95\pm \text{1.10}\,\text{mm}$ deviation with the path driven by the robotic manipulation, which can be further improved by controlling acceleration and velocity. Its real-time performance, ease of use, and potential for AI model training make it valuable for various medical applications, including ultrasound-guided procedures and motion analysis.
