The dynamic structure factor of the spin-$\frac{1}{2}$ transverse Ising chain is obtained by means of a numerical approach suggested earlier [O. Derzhko and T. Krokhmalskii, Ferroelectrics 192, 21 (1997)]. Frequency shapes of the dynamic structure factor at various values of the wave vector, transverse field, and temperature are displayed and discussed.
