摘要：

The tomographic approach to quantum mechanics is revisited as a direct tool to investigate the violation of Bell-like inequalities. Since quantum tomograms are well defined probability distributions, the tomographic approach is emphasized to be the most natural one to compare the predictions of classical and quantum theory. Examples of inequalities for two qubits and two qutrits are considered in the tomographic probability representation of spin states.
