Calibrating Ultrasonic Computed Tomography System Using a Modified GPS Algorithm
Original language description
This paper presents a new method for geometrical self-calibration of an ultrasonic computed tomography (USCT) system. The algorithms used here are based on the so called pseudo-range equations used in the global positioning system (GPS) navigation. Ultrasonic transmitters and receivers in USCT can be viewed as satellite transmitters and mobile receiver units in GPS. However, unlike in GPS, the positions of both transmitters and receivers in USCT are not known. The presented method is capable of calibrating positions and time delays of all ultrasonic transducers at once. No calibration phantoms are necessary.
