Thermoacoustic imaging is a promising new modality for nondestructive evaluation. So far point measurement data for thermoacoustic imaging are used. In this paper we propose a novel measurement set-up with relatively large piezo foils (planar receivers) and an according real time imaging algorithm based on the Radon transform. We present numerical simulations for simulated and real world data.
