Abstract
A method is provided for generating ultrasound transmission waves comprising: a) providing an array of electroacoustic transducer elements each one being connected to an electric excitation signal generator by a dedicated feeding channel; b) feeding at least a part of the electroacoustic transducer elements with a pulsed electric signal having a predetermined frequency, a predetermined amplitude, a predetermined length or duration and a predetermined phase or a predefined delay with respect to the pulsed electric signals fed to the adjacent transducer elements, the said pulsed electric excitation signals comprising a sequence of pulses; c) modulating each or at least part of the pulsed electric signals by feeding to the transducer elements only a predetermined portion of the pulses of the said pulsed electric signals. Modulating is carried out by cutting the duration of each pulse of the pulsed electric excitation signal according to a predetermined time period.
