Abstract
The present report summarizes the results of this project on pulse optimization for ultrasound brain imaging. Three contributions are detailed: a rigorous connection is made between electromagnetic pulse optimization in dispersive media via the Brillouin precursor theory and acoustic pulse optimization for propagation in biological media; bounds, taking into account statistical variability, are stated for the gains in transmitted power that are enabled by employing optimized pulses instead of typical modulated Gaussian pulses; a viable route towards constructing these optimized pulses in practice is outlined and demonstrated through simulation. The report includes a detailed manual for a software package that can be used to analyze realistic head models via the Finite-Difference Time-Domain method.
