Cursor movement method and device for medical display and medical equipment

Abstract

The invention discloses a cursor movement method and device for medical display and medical equipment and belongs to the field of medical display. The method comprises: when receiving a first operation instruction and a movement distance of a first target being greater than a first pre-set threshold value, moving a cursor on a display screen for grids with a pre-set quantity, namely the movement distance of the first target corresponding to the quantity of the movement grids of the cursor on the display screen; when receiving a second operation instruction, changing the size of the pre-set quantity corresponding to the first pre-set threshold value, so as to change a movement distance of the cursor, corresponding to the movement distance of the first target, on the display screen under the condition that the size of the pre-set quantity of the grids is not changed, namely adjusting the size of the movement distance of the cursor, corresponding to the movement distance of the first target, on the display screen by a user according to distances between the cursor and a target position. The cursor gets close to the target position limitlessly, and the accuracy of cursor movement and the operability of the user are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical display, and in particular to a cursor movement, device and medical equipment for medical display. Background technique [0002] With the development and application of medical imaging technologies such as computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound (US), traditional two-dimensional images only express the anatomical information of a certain section, while three-dimensional visualization technology is through Two-dimensional and spatial information constructs the relationship between the size and shape of human organs, soft tissues and lesions, and the location of surrounding tissues, which can assist doctors in diagnosis and treatment more vividly and three-dimensionally, and improve the accuracy and efficiency of diagnosis and treatment planning. Therefore, 3D visualization technology is being used more and more More and more used to assist do...

Problems solved by technology

[0005] In the process of implementing the above technical solution, the inventor found that the moving distance of the cursor on the screen and the moving distance of the user's gesture in the corresponding direction correspond to each other, that is, the user's gesture moves a unit length in the corresponding direction, and the cursor moves on the screen. Also move the unit length along this direction. When the distance between the cursor and the target is not an integer multiple of the unit length, the cursor can never move to the position of the target, that is, the cursor can only move to a position near the target, which cannot meet the requirements of computer-aided medical treatment. Precise positioning of the target position in the display

Moreover, in the process of implementing the above technical solution, the inventor also found that the cursor has a high degree of freedom of movement, and at the same time, the cursor will move with the slight shaking of the user's hand, and is more sensitive to the shaking of the gesture, so it is not sensitive to the movement of the user's gesture. The precision requirements are also high, resulting in difficult operation and low positioning accuracy, and after the cursor is positioned at the target position, if the user's gesture shakes slightly, the cursor will fly away from the target position with the shaking of the user's gesture, stable lower sex
