Embodiment Construction
[0036] Such as figure 1 Shown is a schematic flow chart of the method of the present invention: the fracture line map drawing method based on 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, reset, render and convert the input CT data into a two-dimensional image, thereby extracting the outer contour and fracture line features; figure 2 shown;
[0038] S2. For the preprocessed image obtained in step S1, extract the outer contour, complete the division of fracture blocks, extract the fracture line, and determine the feature points of the outer contour; specifically, use the edge detection algorithm to extract the outer contour on the image, and then use clustering The algorithm completes the division of the fracture block and the extraction of the fracture line, and finally uses the sine function sampling algorithm to sample the o...

The invention discloses a fracture line map drawing method based on an image deformation technology. The method comprises the steps: preprocessing input fracture CT data; extracting the outer contourof the preprocessed image, and completing the division of fracture blocks, the extraction of fracture lines and the determination of outer contour feature points; performing triangulation according tothe feature points to generate a triangular network and adjust an image area; traversing the whole triangular network and carrying out separate adjustment and scaling adjustment on each triangle; andperforming image deformation on the different bone samples based on the outer contour under the condition of ensuring that the internal fracture line characteristics are not changed, thereby unifyingthe bone samples to a standard bone template and finishing drawing of a fracture line map. According to the invention, the fracture line map can be rapidly drawn, the dependence is high, and the accuracy is good.
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] As the most common skeletal injury, fracture injury is mainly caused by high-energy damage to the bone caused by external force, and its physiological manifestations are fractures and bone cracks. After the fracture occurs, if the diagnosis and treatment or care is not proper, it is very 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. The fracture line map drawing technology is a method of superimposing the fracture lines of multiple cases on a bone model through computer image simulation, so as to redisplay the fracture morphology. Its feature is that it can intuitively disp...
