摘要：
A multiobjective optimization method is proposed that uses the weighted sum problem in order to deal with medical image reconstruction from projections. After determining the objective functions, a satisfactory solution of the decision maker is derived by updating the weighted coefficients simultaneously with the tradeoff between the objective functions. The multiobjective approach is superior to the least-squares and convolution methods. The approach makes traditional image reconstruction from projections flexible and robust to uncertainty and multiplicity of reconstruction objectives.
