Abstract
There are disclosed systems for calibrating a first position measuring component on an imaging or scanning transducer with respect to the scanning plane. Calibrations are performed by using a calibrating device including an additional or second position measuring component, such that during the calibration process, the relative position of betweenn these position measuring components can be calculated. Calibrations are also performed by viewing targets on the scanning plane that are at a known position with respect to the second position measuring component. Calibrations are also performed based on the scanning plane and position measuring components on a guided device, such as a needle, that typically is used in conjunction with the imaging or scanning transducer. Methods for these calibrations are also disclosed.
