However, it rotates the 3D reconstructed contour image to a suitable position, prints it out in equal proportions, and sticks it on the surface of the scalp to guide the positioning during surgery. Therefore, only 2D plane guidance can be performed, not 3D guidance.

Embodiment Construction
[0023] see Figure 1 to Figure 5 As shown, the implementation method of the recognition image patch for craniotomy body surface incision navigation of the present invention includes the following steps:
[0024] S1. Obtain a 2D medical image slice set of a patient's cranium, and reconstruct a 3D model including the scalp, veins and lesions, and then hide the scalp, as in figure 2 As shown, only the veins and lesions are displayed in the later stage.
[0025] S2, such as Figure 3a As shown, a recognition image is imported into an augmented reality software development kit, such as Vuforia (Vuforia Augmented Reality SDK in English), to obtain the code of the recognition image; the recognition image is used for camera recognition Display the AR model or animation after arriving at a specific location. The recognition map must have characteristics, high resolution, and low repetition rate, such as image 3 As shown, the two-dimensional code image is more suitable, so that eac...

The invention provides a movable augmented reality navigation method for an incision of a body surface in a craniotomy. A skull part two-dimensional medial image slice set of a patient is obtained, and a three-dimensional model is reconstructed; a recognition image is imported into an augmented reality software development kit, an obtained code and the obtained three-dimensional model are importedinto a Unity 3D development platform, and the proportion and relative position relation of the three-dimensional model and the recognition image are set; APP is exported from the Unity 3D developmentplatform and issued in an intelligent mobile terminal; meanwhile, the recognition image is printed according to the proportion of 1:1, so that a recognition image patch is obtained; according to theposition relation of the three-dimensional model and the recognition image, the recognition image patch adheres to the scalp of a patient; during the operation, the intelligent mobile terminal is holdby hand to adhere to recognition image of the scalp of the patient, then the three-dimensional model after the scalp part is blanked can be displayed, and the display effect of the three-dimensionalmodel corresponds to the position of the relative recognition image of the handheld intelligent mobile terminal. The method is easy to operate, short in positioning time and quite low in cost.
Description
technical field [0001] The invention relates to the field of computer-aided surgery, in particular to a method for assisting the positioning and navigation of body surface incisions in craniotomy. Background technique [0002] Craniotomy, also known as craniotomy, is a kind of cranial surgery, which refers to opening the patient's skull through mechanical equipment, so as to perform some unconventional treatments, such as brain tumor removal. [0003] Before performing a craniotomy, CT and other image scans must be performed on the patient to find the lesion, formulate a surgical plan, and then perform the operation. One of the processes involved is to locate the position of the surgical incision in the image on the computer to the actual patient's head. At present, the most commonly used instrument in major hospitals is the optical positioning surgical navigator. Although the positioning and navigation function of the optical positioning surgical navigator can meet the nee...
