Abstract: Classic computed tomography techniques like ART are widely used for reconstruction of objects scanned in X-ray devices, where almost every object can be made transparent by increasing radiation power and its absorption can be measured with some accuracy. But the classic model cannot be applied to reconstruction of objects which absorption is so high that it does not transmit any radiation: such cases are possible in X-ray tomography with a low-power radiation source and also are frequent in optical tomography.
The article explains difficulties faced by classic ART algorithms in optical tomography in case of opaque regions presence in the scanned object. The ART method modification is proposed for this case.
