Non-contact calibration technique of ultrasound tomography system for complex shaped objects

Robot-assisted ultrasound tomography is an up-to-date technology that provides effective quality assurance of complex shaped objects. However, this method of control requires appropriate calibration of the equipment. At present, calibration is a difficult time-consuming procedure. This paper discusses novel approach – using non-contact calibration technique. The proposed method is based on the preliminary received 3-D reconstruction results. It is proved that non-contact calibration of ultrasound tomography system is more applicable and provides reliable measurement results.
