Abstract
Provided is a diagnostic ultrasound system producing an image whose brightness is enhanced by a contrast medium by implementing contrast echography based on intravenous injection. A diagnostic ultrasound system comprises a probe for converting an electrical driving signal into a corresponding transmission ultrasound wave and converting an echoed ultrasound wave into a corresponding electrical echo signal. The system still comprises a unit for transmitting the transmission ultrasonic wave to a subject by providing the probe the electrical driving signal substantially consisting of a fundamental component of a given driving frequency. The non-fundamental component is typically a second harmonic. A non-fundamental component of the driving frequency is intentionally lowered in power relative to the fundamental component by a suppressing element in the transmitting unit. The system comprises a unit for receiving the echo signal from the probe and processing the echo signal into a display image data reflecting both the fundamental and non-fundamental components and a unit for displaying the display image data.
