5 is a diagram illustrating one embodiment of a Doppler image 500. The Doppler image 500 shown in Figure 5, includes a blood flow Doppler image that represents the flow of blood. That is, the first region 510 and second region 520 of the Doppler image shown in Figure 5, shows the blood flowing through the blood vessel. Further, in FIG Doppler image 500 shown in Fig. 5, arrow 511 and arrow 512 shows the direction of blood flow. That is, the target chain blood is the liquid flows in the direction of arrow 511 in the first region 510, and flows in the arrow 512 direction of the second region 520.

On the other hand, in a Doppler image 500 shown in Figure 5, the probe 505 is located at the top on the basis of the Doppler image 500. That is, the blood shown in the first region 510 is moving in the direction approaching to the probe 505, and the blood shown in the second area 520 moves in a direction away from the probe 505. On the other hand, since the first region 510 and the move in a direction perpendicular to the ultrasound signal at an intermediate point of the second region 520 is connected to the target chain, the blood that is released from the probe 505, the Doppler data is not acquired .

According as the ultrasonic medical device 100 and video display device 200 may display the Doppler image 500 on the display, using a color map (color map) for matching the direction of the target object is moving on the color values, the first region It may represent (510) and a second area 520 in color.

6 is a view showing an example of displaying a marker that indicates the direction of movement of the target object in the Doppler image 500.

First, the ultrasonic medical device 100 determines the direction of movement of the target object by analyzing the Doppler data for the Doppler image 500. For example, an ultrasonic medical device 100 may determine the direction of blood flow by using the code elements included in the Doppler data. Specifically, the sign of the Doppler data for the first region 510 shown in Figure 5 is to "+", the sign of the Doppler data for the second area may be obtained by (or reverse) "." Accordingly, the ultrasonic medical device 100 in the second direction to approach the moving direction of the first region 510 to the probe, it is possible to determine the direction of movement of the second region 520 in a first direction away from the probe.

As also described in the first, the ultrasonic medical device 100 may determine the direction of movement of the target object by using the value components contained in the Doppler data. For example, if "90" This figure component of from 0 to 127, the ultrasonic medical device 100 may determine the direction of movement of the target object in a direction toward the second direction, i.e. the probe. On the other hand, in the case of a "200" a value component, 128 to 255, the ultrasonic medical device 100 may determine the direction of movement of the target object in the first direction, i.e. a direction away from the probe.

On the other hand, the image display apparatus 200, and can determine the moving direction of the target object based on color values ​​in place of, the Doppler image 500 using the Doppler data, as described above. That is, for a period of within a first predetermined range indicating the color value is red in the Doppler image 500, video display device 200 may determine the direction of movement in the second direction. Conversely, if the color value is within a predetermined second range representing the blue video display device 200 may determine the direction of movement in a first direction away from the probe.

Then, the ultrasonic medical device 100 and video display device 200 may display the at least one marker that indicates the direction of movement of the target object in the Doppler image 500. That is, in the embodiment shown in Figure 6, the ultrasonic medical device 100 and video display device 200 indicates the movement direction and displays the marker of the arrow shape. On the other hand, the arrow shape shown in Figure 6 is merely one embodiment of the marker, the ultrasonic medical device 100 and video display device 200 may display a variety of other types of markers which can show the direction .

The Since the second direction approaching to the direction of blood flow probe in the first region 510, the ultrasonic medical device 100 and video display device 200 for indicating the second direction (i.e., upward direction towards the probe) It may indicate at least one of the marker 515 in the first area 510 of the Doppler image 500. On the other hand, the ultrasonic medical device 100 and video display device 200 is the second of the Doppler image by using at least one marker 525 to illustrate that the first direction of the blood for the second region 520 away from the probe region may represent a direction of movement of the object of 520.

According to the the other hand, another embodiment related to Figure 6, the ultrasonic medical device 100 and video display device 200 is a direction of the at least one marker to face the center of the probe or away from the center of a probe represented by a predetermined distance It can be displayed facing. That is, for the marker 515 shown in the first region 510 of FIG. 6 for example, there is shown both Figure 6 shows markers 515 are facing in the same direction (upper vertical direction). However, the ultrasonic medical device 100 and video display device 200, a marker 515 indicating the (direction approaching the probe) the same direction of movement can be displayed by display toward the probe, each of the markers at different angles is.

7 is a view showing an example of displaying the marker according to the depth axis 530 of the Doppler image 500. 7, the depth-axis (530) contained in a Doppler image 500 is shown. That is, the depth of shaft 530, it is possible to sense the linear ultrasonic signal emitted by the probe 505 to be delivered to a subject, in accordance with the Doppler image 500 is being flat form non-rectangular, axes each depth ( 530) are not parallel to each other.

According to one embodiment, each of the depth axis 530 it is contained in the Doppler image 500 is an ultrasonic signal emitted by the probe 505 may indicate a scan line to scan the object. On the other hand, the depth direction of the axis 530, can refer to the ultrasonic signals away from the probe 505 (i.e., downward direction in Fig. 7) direction. 7, the bottom end of each of the depth axis 530, the arrows indicating the depth-axis direction is shown.

In the embodiment shown in Figure 7, the ultrasonic medical device 100 and video display device 200, the display along at least one of a marker that indicates the direction of movement of the target object in the depth-axis (530) of the Doppler image 500 .

In Figure 7, the contrast, the ultrasonic medical device 100 and video display device 200 may display along at least one of the markers on the depth axis 530, so that one or more markers 516 of the first region 510 are (in Figure 7, the second direction approaching the probe) even if the same moving direction indicate, respectively, the angle at which the display can be different.

More specifically, in FIG. 6 the depth axis 530 is shown in 7, it represents the marker 516 in the same direction of movement (in the direction towards the probe, the second direction) shown in the three-axis depth on the left side. However, since not parallel to each other due to the three depth axis sector form a Doppler image 500 of the left, the angle displayed on the markers 516, the Doppler image 500 is displayed in three depth axis on the left side may be different from each other, .

Similarly, the markers shown in the three axes of the right depth in the six-axis depth 530 526 shows a direction (that is, the depth of the axial direction, a first direction) away from the probe. Does not right axis also parallel to each other three-axis depth, the ultrasonic medical device 100, the markers 526 represented according to three depth axis right, and in accordance with each of the depth axis may be represented by a different angle.

In addition, the ultrasonic medical device 100 and video display device 200 may display a predetermined interval along the depth markers on the shaft 530. Interval of at least one marker ultrasonic medical device 100 and video display device 200 for displaying based on the depth axis 530 can be adjusted by the internal system, or user input.

On the other hand, the ultrasonic medical device 100 and video display device 200 can display in accordance with the marker on the depth axis 530, the display marker to the scan line interval of a predetermined number. That is, a six-axis depth of 530 shown in Figure 7 can be respectively correspond to the scan lines has been described above. Thus, the depth axis 530 marker is displayed can be determined for each scanning line a predetermined number. For example, an ultrasonic medical device 100 and video display device 200 may display a marker of 20 scan lines from the scan line interval in the left end of the Doppler image 500. Ultrasonic medical device 100 and video display device 200, similarly to those that can adjust the interval of the marker displayed on the depth axis 530, and may adjust the interval of scan lines.
