| Abstract: | Image reconstruction algorithm is the key technology of electrical capacitance tomography system research. It is necessary to look for a kind of image reconstruction algorithm which can meet the requirements of industrial application in image reconstruction speed and quality. The conjugate gradient algorithm based on trust region method is a new image reconstruction al？gorithm proposed on the basis of the general conjugate gradient algorithm. It improved the speed and quality of image reconstruc？tion. |
