Abstract

Iterative regularization method to process captured data by color Doppler flow mapping has been proposed. It takes into account features of the ultrasound investigation and allows to solve the problem even in the case of noisy data and in the case of existing areas with unknown flow values. The influence of the values of regularization parameters on the obtained solution was analyzed. Test results for the left ventricle color Doppler flow mapping investigation showed effectiveness of the algorithm.
