Abstract: We consider the problem of multifrequency VLBA image synthesis andspectral-index mapping for active galactic nuclei related to the necessity oftaking into account the frequency-dependent image shift. We describe ourgeneralized multifrequency synthesis algorithm with a spectral correction basedon the maximum entropy method. The results of our processing of multifrequencyVLBI data for the radio sources J2202+4216, J0336+3218, and J1419+5423 arepresented.
