Embodiment

[0039] A lesion registration method for a high-precision surgical navigation system. First, a medical image scanner is used to obtain image data of a patient's lesion. The original image data includes CT or MRI data in dicom format, and then the patient's lesion is reconstructed by a medical three-dimensional model reconstruction system. Three-dimensional reconstruction, the reconstruction tool adopts the software that can complete the reconstruction of the medical model. In this embodiment, the mimics software is used for reconstruction; since the image data in the dicom format has its own coordinate system, the origin of the coordinate system is generally at the lower corner of the CT machine. The coordinate systems of brand CT machines are also different. The coordinate system of the image data can be determined according to the actual CT machine used. In the 3D reconstruction software, the model will be reconstructed according to the origin of the actual CT machine. The orig...

Abstract

The invention relates to the technical field of medical treatment, and particularly discloses a focus registration method of a high-precision surgical navigation system. The method comprises the steps of focus three-dimensional reconstruction, tracking unit setting, model combination, positioning ball installation, model origin matching and the like. According to the method, a complete model origin with a positioning ball is adjusted to be matched with an origin of optical positioning equipment software, so that a tracking object in a complete model coincides with a tracking object entity model, and registration of a patient focus is completed; and accurate adjustment is performed through deviation calculation, so that the precision difference can be reduced, the registration precision is effectively improved, and the registration method better meets the requirements of minimally invasive surgery.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a lesion registration method for a high-precision surgical navigation system. Background technique [0002] At present, the use of optical navigation equipment is to obtain real-time six-dimensional information of the target object in real space (the position and rotation information of the three coordinate axes x, y, z), so that the model objects in the virtual space can also obtain the same information. Match the coordinates of the real space with the coordinate system of the virtual space. If multiple objects need to be spatially positioned using an optical navigation device at the same time, the matching accuracy of the objects will become a problem that needs to be solved. There are two long strip objects A and B in the real space, and there are two models xA and xB of the same shape in the virtual space. In the real space, A and B maintain a relative posture, and the real...
