Cursor movement method and device used for medical display and medical device

Abstract

The invention discloses a cursor movement method and device used for medical display and a medical device, and belongs to the field of medical display. The method includes the steps that a preset grid is constructed on a display screen, a cursor is controlled to move on nodes of the preset grid so that the degree of freedom of cursor movement can be limited, accordingly the distance and the direction of cursor movement are more explicit, deviation does not occur, a cursor is prevented from being interfered by jitter of a first target, stability of cursor movement is improved, and the requirement for movement precision of the first target is lowered in the cursor moving process. Meanwhile, the preset grid with first resolution is constructed with the position where the cursor is located as the center, it is guaranteed that the cursor is located in the center of the preset grid, accordingly the cursor has a large moving range in any direction of the preset grid with the first resolution, and the cursor can quickly move to any area of a display interface, can be conveniently and quickly positioned at any target position and can be quickly positioned to any target position even if at an operation focus.

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
