Embodiment Construction
[0051] Such as figure 1 As shown, it is a flow chart of the steps of the surgical navigation method of an embodiment, including the following steps:
[0052] Step S101, before the operation, the preset breathing point of the human body is obtained through the breathing gating method.
[0053] In this embodiment, the preset breathing point is the point of maximum inhalation. Because the patient can hold their breath for a long time at this time, and it is easier to control the same breathing stage multiple times, so as to reduce the impact of breathing on subsequent organ imaging.
[0054] Step S102, at the preset breathing point, collect the three-dimensional image of the organ by way of MRI or CT, and display it in the preoperative coordinate system.
[0055] Because there is more time before the operation, MRI or CT and other clear imaging methods are used here for image acquisition.
[0056] Step S103, segmenting the 3D images of organs according to different tissues.
