Abstract
An imaging system and method for determining sensor position and orientation with respect to an object having a known three dimensional structure is disclosed. The sensor acquires an image of the known structure. Position and orientation of the sensor is determined by processing the image with formulas corresponding to the known structure. One embodiment of the present invention comprises an ultrasound training system and method for determining the position and orientation of an ultrasound probe with respect to a known three dimensional structure embodied in an ultrasound phantom. The ultrasound probe acquires a cross sectional or partial volume image of the ultrasound phantom. The image is processed to obtain a number of geometrical image parameters. Position and orientation of the ultrasound probe are calculated from the image parameters using formulas based on the known three dimensional structure. The determination of probe position and orientation may be enhanced using image de-correlation techniques.
