Abstract
A method for calibrating an ultrasound probe includes receiving, from the ultrasound probe, data of a target within a test fixture, wherein the target includes a repetitive pattern along two axes; generating a first ultrasound image of the target; and identifying distortion of the target in the first ultrasound image. The method also includes estimating, based on identifying the distortion, offset parameter values for one or more of three angular errors within the ultrasound probe; generating a second ultrasound image of the target using the offset parameter values; identifying corrected distortion of the target in the second ultrasound image; and storing the offset parameter values.
