Apparatus and method for image guided accuracy verification

Abstract

A method includes receiving during a first time interval image data associated with an image of a dynamic body. The image data includes an indication of the positions of a first marker and a second marker on a garment coupled to the dynamic body. The first marker and second marker are each coupled to the garment at a first and second locations, respectively. A distance is determined between the position of the first marker and the second marker. During a second time interval after the first time interval, data associated with a position of a first and second localization element that are each coupled to the garment is received. A distance between the first and second localization elements is determined. A difference is calculated between the distance between the first marker and the second marker and the distance between the first localization element and the second localization element.
