The possibility of using a future measurement of the ratio [ital B]([ital B][r arrow][rho][gamma])/[ital B]([ital B][r arrow][ital K][sup *][gamma]) to improve the constraints on the CKM parameter [vert bar][ital V][sub [ital t][ital d]][vert bar] is investigated. Special attention is paid to the two main sources of theoretical uncertainties: the SU(3) flavor symmetry-breaking effects and the contribution from final-state interactions.
