Abstract ：Motivated by the recent ATLAS results in terms of the branching ratios $ Br(t\rightarrow q\gamma)$, we consider the effects of the anomalous $tq\gamma$ couplings on the radiative $B$ meson decays $\bar{B}\rightarrow X_{D} \gamma$ and $B\rightarrow V\gamma$ with $V$ being light vector mesons $\rho,\omega,\phi$ and $K^{\ast}$. Comparing with the corresponding experimental measured data, we obtain the constraints on anomalous $tq\gamma$ couplings.
