Claims

[Claims for Utility Model Registration] (1) Having a transmitting/receiving unit that drives at least one probe, receiving reflected waves of sound waves from the subject,
Image data for B-mode display is extracted from the intensity data of the reflected wave, and image data of the moving object of the subject is selectively extracted from the change in the reflected wave, and both image data are combined. In a moving object detection and display device that writes or displays information on a DSC via a frame memory, a location where a high degree of change in pulsation that is similar to cardiac arrest in video data of a moving object in the frame memory is recognized is determined to be an artery; a change amount calculation means for determining that a portion where the pulsation is not highly recognized is a vein, and a portion that is determined to be at least an artery according to the judgment result of the change amount calculation means, and a portion that is determined to be a vein. A moving object detection and display device characterized in that it has a color determination table in which the portion is colored blue and is superimposed on the video data of the DSC. (2) The change amount calculation means inputs an electrocardiogram signal,
2. The moving object detection and display device according to claim 1, wherein the classification judgment is made by comparing video data in the ST interval of the electrocardiographic signal with video data in other intervals.
