Abstract
A method of calibrating a transformation of ultrasound data in an imaging system from a first coordinate system into a second coordinate system, the method including applying a transformation having parameters. The parameters are calibrated by imaging a planar object, extracting points corresponding to ultrasound rays intersecting the planar object, and fitting the parameters such that the points when transformed by the transformation describe a planar surface in the second coordinate system.
