Laser-driven ion sources represent a promising particle acceleration option for many interesting fields in physics, chemistry and biology. The properties of laser-accelerated ion bunches - especially the short and intense particle pulses with a broad energy spectrum emitted in conjunction with a strong electromagnetic pulse - demand the development of suitable beam diagnostics. The innovative approach of measuring the acoustic signals of particles depositing their energy in water, referred to as Ion-Bunch Energy Acoustic Tracing (I-BEAT), was already demonstrated to be capable of reconstructing also complex energy spectra at the ion focus while being radiation and EMP resistant. Here, an extension of the set-up for multidimensional dose reconstruction is presented. First experimental tests show promising results as e.g. the determination of the lateral beam position with sub-millimetre accuracy.
