Abstract In order to solve the nonlinear ill-posed inverse problem of electrical capacitance tomography (ECT), a multi-scale adaptation network (MSANet) model is proposed, which achieves the fusion of multi-scale features in a more fine-grained dimension and has a relatively small number of model parameters.By constructing a tree structure within a single residual block to form a multi-scale feature fusion module, MSANet achieves more robustness and lower computational parameters. Furthermore,by adding an adaptive spatial threshold module, the reconstruction accuracy of the images is further improved. Compared with linear back projection (LBP) algorithm, Landweber iterative algorithm,and commonly used deep learning methods, this method has the smallest average relative error and the largest average correlation coefficient,with 0.181 and 0.967, respectively.
