Abstract
An ultrasonic image scanning system for scanning an organic object by projecting ultrasound signals with a transmit carrier frequency. The ultrasonic image scanning system includes a switching mode power supply operated with a programmable clock in synchronization with the transmit carrier frequency. The switching mode power supply further provided with circuits for generating a low voltage and a high voltage. The ultrasonic image scanning system further includes transducers for projecting ultrasound signals wherein the transducers are connected to and electrically excited by the high voltage generated by the switching mode power supply. The switching mode power supply further includes a DC-to-DC switcher having an external clock input for clock synchronization. The programmable clock further provided for receiving a user command to operate with the switching mode power supply in synchronization with the transmit carrier frequency
