| Abstract: | An improved convolution algorithm has been developed for rapid con- structing CT image,and an ideal numerical method to produce analog projecting signal is presented.The effect of different filtering functions and interpolation algorithms is exam- ined and the quality of reconstruction images is satisfactory.At last,ultrasonic nonlinear images are reconstructed successfully by using the algorithm. |
