Abstract:
1. A high voltage generator configured for use in an ultrasonic image scanning system for scanning an organic object by projecting ultrasound signals at a transmit carrier frequency comprising: a switching mode power supply; a direct current-to-direct current switching voltage generator in electrical communication with the switching mode power supply; a programmable clock comprising a transmit carrier frequency input, the programmable clock in electrical communication with the switching mode power supply and the direct current-to-direct current switching voltage generator, the programmable clock synchronized with the transmit carrier frequency and configured to synchronize the switching mode power supply and the direct current-to-direct current switching voltage generator such that a change in the transmit carrier frequency causes the programmable clock to sync the switching mode power supply to the changed transmit carrier frequency; a system controller configured to control said programmable clock configured for syncing upon a change in pulse repetition period in Color mode or Doppler mode; and a digital programmable counter, the digital programmable counter configured to receive a command from the system controller to set up a divided down ratio configured to divide and generate a switching clock signal input to the switching mode power supply.
