Problems solved by technology

However, the inventors found that the current research on human body model simulation is limited to the visualization stage, and in the aspect of custom control of human body model visualization, it is mainly aimed at the color assignment of two-dimensional profile diagrams, and lacks custom control means for three-dimensional models
The existing model editing software, such as 3Dmax, unity, etc., can set the display parameters by selecting lines, surfaces or three-dimensional structures composed of surfaces in the model, so as to realize the display control of some models, but this display method is mainly for A 3D model composed of multiple basic models, not suitable for mannequins created from medical images

Abstract

The invention discloses a displaying regulating method of a human body organ model and a system. The method comprises the following steps of receiving medical image data and performing three-dimensional reconstruction; displaying a three-dimensional model in a preset color mode, and simultaneously displaying a displaying regulating area which displays a correspondence relation between a color thatcorresponds with the current color mode and image density; receiving an editing operation which aims at the correspondence relation between the color and the image density in the displaying regulating area, thereby obtaining a new color mode and applying the new color mode to the three-dimensional model. The displaying regulating method can realize color enhancement for aiming at a specific organtissue or focus in a three-dimensional model, thereby facilitating observing of the specific organ tissue or the focus by a doctor and performing surgery pre-navigation.

Description

technical field [0001] The invention belongs to the technical field of surgical auxiliary medical systems, and in particular relates to a display control method and system of a human organ model in a surgical simulation system. Background technique [0002] Surgical simulation system is a typical application of virtual reality technology in the medical field. At present, it is mainly used in the following scenarios, a) is used in the virtual surgery training and teaching system. b) is used in the simulation experiment of surgical robot; c) is used in the operation planning system. The virtual human body simulation system starts from medical image data and uses computer graphics to reconstruct a virtual human body soft tissue model. The virtual surgery system provides doctors with a virtual 3D environment and an interactive operating platform, realistically simulating the whole process of clinical surgery. Virtual surgery has the advantages of non-invasive, repeatable and ...
