Compressed sensing is a promising approach for significantly reducing the number of measurements in photoacoustic tomography (or other limited data imaging problems) while preserving its high spatial resolution. In this talk we present a new sparse recovery framework for recovering the photoacoustic source from compressive measurements. Results with simulated as well as experimental data are given.
