抄録

Ultrasonic CT has been applied to visualize the temperature field as a kind of nonintrusive method. This research tries to develop a new ultrasonic CT reoonstruction method based on inverse matrix transfer which differs itself from the ordinary CT reconstruction, known as FBP(Filtered Back Projection) with SL Filter, in the way of dealing with problems such as having not enough projection data due to limited projected angle. In current paper, 3 kinds of iterative CF reoonstruction algorithm are described. Computer simulations are oonducted to verify the above algorithm and the reoonstruction results are oompared. According to the simulation results, CGM (Conjugate Gradient Method) is confimied to be the most optimum iterative way and find will find its use in our further experimental stage.
