We present an open-source MATLAB toolkit for ultrasound calibration. It has a convenient graphical user interface which sits on top of an extensive API. Calibration using three different phantoms is explicitly supported: the cross-wire phantom, 1 the single-wall phantom, 2 and the Hopkins phantom. 3 Image processing of the Hopkins phantom is automated by making use of techniques from binary morphology, radon transform and RANSAC. 4 Numerous calibration and termination parameters are exposed. It is also modular, allowing one to apply the system to original phantoms by writing a minimum of new code.
