Ultrasonic Computed Tomography for Noninvasive Temperature Measurement

Yang Yihong;Wang Hongzhang  
A method for measuring the internal temperature of the human body by ultrasonic computed tomography UCT is presented. The measurement of tem- perature was carried out by using a proper model, which corresponds to an ultra- sonic CT arithmatic calculation process. The precision of the measurement and the duration of UCT calculation were analyzed. Two methods of reiteration for the incomplete data due to wave propagation obstructed by bones or air have been adopted. Furthermore, the diffraction UCT with the convolution back-propaga- tion method has also been discussed. A new method for diffraction UCT in the case of obstructed data and the results from computer simulation have been given.
