<p>An embodiment for controlling a power of transmit pulses in an ultrasound system is disclosed. An ultrasound probe contains a plurality of transducer elements for reciprocal conversion between electrical signals and ultrasound signals. A transmitter includes a plurality of pulse generators. Each of the pulse generators is connected to the respective transducer element through a channel to generate a transmit (Tx) pulse at a transmit (Tx) frequency in synchronization with a Tx control clock. Each of the pulse generators has a plurality of pulsers operating at different voltages in response to pulser control signals.</p> |
