Patent ID: 7566304

Claim:
An ultrasound diagnostic device, comprising: an ultrasound generation means that transmits ultrasound; a waveform generation means that generates a driving waveform comprising a single pulse or burst pulses in response to a trigger input, so as to drive the ultrasound generation means; a mode control unit that generates mode information for every transmission; a waveform control unit that sets a pulse width, a wave number and a duty factor of the driving waveform generated by the waveform generation means based on the mode information from the mode control unit so as to correspond to waveform information that is determined for each mode corresponding to the mode information; and a power supply unit that determines an amplitude of the driving waveform generated by the waveform generation means, wherein the single pulse or each pulse of the burst pulses of the driving waveform comprises subsidiary pulses, and a duty factor of the subsidiary pulses is less than 100% of the single pulse or each pulse of the burst pulses and variable in a time period corresponding to a frequency band above a frequency band of the ultrasound generation means.
