Calibration method and apparatus for calibrating position sensors on scanning transducers

A method for calibrating a medical imaging device scanning and imaging plane to a first position measuring component being attached onto said medical imaging device, the method comprising the steps of:

• establishing a reference plane, said reference plane at a first location;
• arranging a target volume identifiable by the medical imaging device scanning transducer, around said reference plane;
• providing a second position measuring component having a known position with respect to said reference plane;
• manipulating said medical imaging device scanning transducer to scan said target volume;
• determining the position of said scanning plane with respect to said reference plane;
• determining the position of said first position measuring component with respect to said second position measuring component;
• and
• processing data corresponding to the position of said first position measuring component with respect to said second position measuring component, and data corresponding to the position of said scanning plane with respect to said reference plane in order to calculate the position of said scanning plane with respect to said first position measuring component.
