Abstract

An ultrasound image displaying method includes creating a 3D image based on B mode data with a high luminance and a low luminance in a B mode image being inverted, creating a color overlaid 3D image by applying colors based on color Doppler mode data only for pixels of the 3D image having a luminance not more than a predetermined value in the B mode image, and displaying the color overlaid 3D image.
