Paper Abstract

This paper presents a real-time, freehand ultrasound (US) calibration system, with automatic accuracy control and incorporation of US section thickness. Intended for operating-room usage, the system featured a fully automated calibration method that requires minimal human interaction, and an automatic accuracy control mechanism based on a set of ground-truth data. We have also developed a technique to quantitatively evaluate and incorporate US section thickness to improve the calibration precision. The experimental results demonstrated that the calibration system was able to consistently and robustly achieve high calibration accuracy with real-time performance and efficiency. Further, our preliminary results to incorporate elevation beam profile have demonstrated a promising reduction of uncertainties to estimate elevation-related parameters.
