B118 超音波ドプラ情報に基づく心臓内血流のベクトル表示と流線表示との比較

抄録

The blood flow in the heart can be observed as a colored image with medical ultrasonic Doppler equipment. As for this image, the component of velocity of the direction of an ultrasonic beam of a blood flow is displayed in blue and red. The component of velocity in an observing plane can be guessed from this component of velocity. This result is displayed according to the purpose. Here, the direct presentation of the flow vector was compared with the streamline display which quantized the blood flow. The vortex of a flow was easier to be observed by a streamline display. It turned out that a vector display tends to grasp the character of a flux.
