When the second touch event is a rightward movement, the first target object 111 can be rotated by an angle θ clockwise with the center point C as the center of the circle. When the second touch event continues to move in a more rightward direction, the first target object 111 can be rotated clockwise by a larger angle. Conversely, when the second touch event is a movement to the left, the first target object 111 can be rotated counterclockwise by an angle -θ with the center point C as the center of the circle. When the second touch event continues to move in the left direction, the first target object 111 rotates counterclockwise by a larger angle. In this way, the angle of the first target object 111 can be adjusted so that the first target object 111 is aligned with the blood flow direction in the blood vessel image 21 (shown in FIG. 2 ) to measure the blood flow rate.

Referring to FIG. 6 , if the second target object 112 is related to blood sampling volume, the second direction D2 may be the movement in the up and down direction on the display screen 100 , and the second control action may be to change the distance between the second target objects 112 to The volume of the second target object 112 is adjusted. When the second touch event is an upward movement, the second target object 112 can move away from the center point C synchronously. When the second touch event continues to move in a higher direction, the second target object 112 can be further away from the center point C. As shown in FIG. Conversely, when the second touch event is a downward movement, the second target object 112 can approach the center point C synchronously. When the second touch event continues to move downward, the second target The object 112 may be closer to the center point C. Thereby, the volume of the second target object 112 can be adjusted, and the user can selectively check the blood flow data in the region of the sampling volume of the second target object 112 along the ultrasonic cursor 10 .

Referring to FIG. 4 , in another embodiment, the prompt indicator 13 may further include a first arrow indicator 131 and a second arrow indicator 132 . The first arrow pointer 131 corresponds to the first direction D1, and the second arrow pointer 132 corresponds to the second direction D2. In addition, the first arrow indicator 131 has the same first appearance as the first target object 111 , for example, the same color; the second arrow indicator 132 further has the same second appearance as the second target object 112 , for example, different from The same color as the first look. Alternatively, the prompting indicator 13 may prompt the user 3 in the form of textual display what behavior mode the user 3 can perform and which target object the behavior mode executes the corresponding control behavior, so as to facilitate the user 3 to operate.

In step s108, the behavior modes of the first touch event and the second touch event may be moved in the same direction. That is, the movement trajectories of the index finger 31 and the middle finger 32 can move in the same direction synchronously. As shown in the operation shown in FIG. 5 , the index finger 31 and the middle finger 32 can move to the right of the display screen 100 synchronously. In the operation as shown in FIG. 6 , the index finger 31 and the middle finger 32 can move toward the bottom of the display screen 100 synchronously.
