摘要： An ultrasound diagnosis apparatus having a transmission circuit which generates a transmission signal is provided. The transmission signal corresponds to a combined waveform of a trapezoidal waveform and an impulse-shaped waveform (impulse portion). In an example transmission signal, a front slope portion, a flat portion, and a rear slope portion exist in a positive polarity side. The impulse portion has a shape which protrudes from an offset level over a base line into an opposite polarity side. Because the center frequency of the trapezoidal wave form is near the DC component, the trapezoidal wave form can substantially be ignored. The impulse portion has a large amplitude, but because the impulse portion exists over both polarities, there is no need to apply a special high voltage countermeasure for each polarity in designing the transmission circuit. A trapezoidal wave form of an opposite polarity may be added in front of the trapezoidal waveform.
