This paper describes a new robust and fully automatic method for calibration of three-dimensional (3D) freehand ultrasound. 3D Free- hand ultrasound consists in mounting a position sensor on a standard probe. The echographic B-scans can be localized in 3D, and can be com- pounded into a volume. However, especially for quantitative use, this process dramatically requires a calibration procedure that determines its accuracy and usefullness. Calibration aims at determining the transfor- mation (translations, rotations, scaling) between the coordinates system of the echographic images and the coordinate system of the localization system. To calibrate, we acquire images of a phantom whose 3D geo- metrical properties are known. We propose a robust and fully automatic calibration method based on the Hough transform and robust estimators. Experiments have been done with synthetic and real sequences, and this calibration method is shown to be easy to perform, accurate, automatic and fast enough for clinical use
