| 摘要 |
An ultrasonic Doppler diagnostic equipment comprising a spectrum measurement unit which measures a Doppler spectrum, a decision unit which determines processing conditions of an average process on the basis of power values of spectral components in the Doppler spectrum, an average process unit which performs the average process of the Doppler spectrum on the basis of the processing conditions determined by the decision unit, and a display unit which displays a Doppler spectral image on the basis of the Doppler spectrum subjected to the average process by the average process unit. According to the configuration, the ultrasonic Doppler diagnostic equipment can improve discontinuities in those spectral components of small power values which are susceptible to interference noise, in the Doppler spectral image, and it can generate image data of high resolution.
