Method and device for displaying internal marker of human organ three-dimensional medical model

Abstract

The invention discloses a method and device for displaying an internal marker of a human organ three-dimensional medical model, which belongs to the field of image processing. A perspective window is arranged on the surface of the human organ three-dimensional medical model, so that the internal marker can be observed from the perspective window. When the model is manipulated to rotate, the position of the perspective window on the surface of the model also changes, so that the marker can always be seen from the perspective window. The marker is set to have the effect of a search light source, and the irradiation effect is that when the model is rotated, the irradiation direction is always back to the perspective window and the light source irradiates the rear surface of the human organ three-dimensional medical model to carry out reflection to form a light spot effect. In the process of rotation, the change in the size of the light spot can reflect the distance between the marker and the rear surface from the perspective window when the human organ three-dimensional medical model is rotated to different positions. According to the invention, the accuracy of the method for displaying the internal marker is improved, and the method and device are used for displaying the internal marker on a display screen.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for displaying internal marker points of a three-dimensional medical model of human organs. Background technique [0002] With the development and application of medical imaging technologies such as computed tomography (English: Computed Tomography; abbreviation: CT), magnetic resonance imaging (English: Magnetic Resonance Imaging; abbreviation: MRI), ultrasound (English: Ultrasonography; abbreviation: US), traditional Two-dimensional images only express the anatomical information of a certain section, while three-dimensional visualization technology uses two-dimensional and spatial information to construct the relationship between the size and shape of human organs, soft tissues, lesions and surrounding tissues, which can assist doctors in diagnosis and treatment in a more vivid and three-dimensional manner. To improve the accuracy and efficiency of diagnosis ...

Problems solved by technology

[0005] Due to the transparency of the 3D medical model of human organs, the visual positions of the marked points inside and on the surface of the 3D medical model of human organs are the same in the display results, and it is impossible to distinguish the real position of the marked points, so that doctors cannot distinguish whether the marked points are located in human organs. Whether the inside or outside of the 3D medical model makes it impossible to view effectively
