Problems solved by technology

[0003] However, in the above method, the moving distance of the trackball is directly related to the moving distance of the cursor in the medical image, and since the moving step of the trackball is relatively large, the moving step of the cursor is also relatively large. The control accuracy is lower, resulting in lower measurement accuracy

Abstract

The invention relates to a cursor control method and device, ultrasonic equipment and a storage medium. The cursor control method comprises the following steps: receiving a moving instruction for a virtual control, where the medical image display interface comprises a medical image and a virtual control, and the virtual control is used for controlling a cursor in the medical image display interface to move; executing a moving operation on the virtual control according to the moving instruction, and obtaining a moving distance and a moving direction of the virtual control; and determining the moving speed of the cursor according to the moving distance, and controlling the cursor to move on the medical image according to the moving speed and the moving direction. According to the cursor control method, the moving position of the cursor is determined by the moving speed and the moving direction of the cursor, and when the cursor needs to stop, the cursor can be controlled to stop at the position where the cursor needs to stop by making the moving speed of the cursor be 0. In this way, the control precision of the cursor is not affected by the control precision of the virtual control, and therefore the control precision of the cursor is improved.

Description

technical field [0001] The present application relates to the technical field of medical equipment, in particular to a cursor control method, device, ultrasonic equipment and storage medium. Background technique [0002] The existing ultrasonic complete equipment includes a display screen and a trackball. A cursor is displayed on the display screen. There is a position mapping relationship between the trackball and the cursor. Based on the position mapping relationship, when the trackball moves, the cursor also follows. move. In application, the display screen is used to display the ultrasound image, and the user moves the cursor by dragging the trackball, and measures the region of interest in the ultrasound image based on the result of the movement of the cursor. [0003] However, in the above method, the moving distance of the trackball is directly related to the moving distance of the cursor in the medical image, and since the moving step of the trackball is relatively ...
