A measurement of the cross section for the production of isolated prompt photons in pp collisions at a center-of-mass energy $sqrt{s} = 7$ TeV is presented. The results are based on an integrated luminosity of 4.6 fb$^{-1}$ collected with the ATLAS detector at the LHC. The cross section is measured as a function of photon pseudorapidity $\eta^\gamma$ and transverse energy $E_T^\gamma$ in the kinematic range $100 < E_T^\gamma < 1000$ GeV and in the regions $|\eta^\gamma| < 1.37$ and $1.52 < |\eta^\gamma| < 2.37$. The results are compared to leading-order parton-shower Monte Carlo models and next-to-leading order perturbative QCD calculations. Next to-leading-order perturbative QCD calculations agree well with the measured cross sections as a function of $E_T^\gamma$ and $\eta^\gamma$.
