Echographic imaging with dynamically focused insonification.
This work describes a real-time echographic imaging device with lateral scanning and a new process for dynamic focusing. While, in reception, a time varying focus is a well-established process, the system that we propose is able to perform dynamic focusing also in transmission. This is carried out by emitting several acoustic pulses focused in different regions. This process, which we call dynamic focused insonification, gives good results and can be used either alone or in connection with dynamic focusing in reception.
