  • Ultrasound diagnosis apparatus for generating an image based on extracted harmonics component
    Patent number: 6146330
    Abstract: An ultrasound wave is transmitted to a target object through an ultrasound probe, and an echo signal returning from the target object is received through the ultrasound probe. In a fundamental wave mode, a fundamental wave component is extracted from the echo signal, and an image is generated based on the fundamental wave component. In a harmonics mode, a harmonics component is extracted, and an image is generated based on the harmonics component. The focal strength ratio of the ultrasound wave in the harmonica mode is changed between in the harmonics mode and in the fundamental wave mode. As a result, images with high quality can be obtained in both the fundamental wave mode and the harmonics mode.
