Embodiment Construction

[0036] like figure 1 Shown is a schematic flow chart of the method of the present invention: the method for drawing a fracture line map based on the image deformation technology provided by the present invention includes the following steps:

[0037] S1. Preprocess the input fracture CT data to obtain a preprocessed image; specifically, model, reduce, render and convert the input CT data into a two-dimensional image, thereby extracting the features of the outer contour and fracture line; such as figure 2 shown;

[0038] S2. For the preprocessed image obtained in step S1, extract the outer contour, complete the division of the fracture fragments, the extraction of the fracture line, and the determination of the outer contour feature points; specifically, the outer contour is extracted by using an edge detection algorithm on the image, and then clustering is used. The algorithm completes the division of the fracture fragments and the extraction of the fracture line, and finall...

Abstract

The invention discloses a fracture line map drawing method based on image deformation technology, which includes preprocessing input fracture CT data; Determination of points; triangulate according to feature points to generate a triangular network and adjust the image area; traverse the entire triangular network and adjust and scale each triangle separately; separate bone samples to ensure that the internal fracture line features remain unchanged. In this case, the image is deformed based on the outer contour, so as to be unified into the standard bone template to complete the drawing of the fracture line map. The invention can quickly draw a fracture line map, and has high reliability and good accuracy.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a fracture line map drawing method based on image deformation technology. Background technique [0002] Fracture injury is the most common bone injury. The main reason is that the external force causes high-energy damage to the bone. After a fracture occurs, if the diagnosis and treatment or care is not appropriate, it is easy to cause many complications. The fracture morphology of each part is closely related to the clinical treatment effect. Therefore, the fracture line map can provide a comprehensive and intuitive description of fracture characteristics. Fracture line mapping technology is a method of superimposing fracture lines of multiple cases on a bone model through computer image simulation, so as to display the fracture shape again. Its characteristic is that the "big data" of a certain fracture can be displayed intuitively, including information such as t...
