Problems solved by technology

However, at this time, the patient's bone tissue is different from the bone tissue in the CT scan data, so registration can no longer be performed according to the above registration method, so the application of the above registration method is low

Abstract

The present application relates to a registration method, device, computer equipment and storage medium for surgical navigation. The method obtains at least two X-Ray images taken by the patient's CT image and the C-arm in different postures, and dissects the patient according to the imaging parameters of the C-arm in different postures and the corresponding X-Ray images in different postures. The pixel coordinates of the points are used to determine the coordinates of the anatomical points in the surgical coordinate system. Finally, the target registration parameters are determined according to the spatial coordinates of the anatomical points in the CT image and the coordinates of the anatomical points in the surgical coordinate system. The above method realizes the application of the C-arm in the registration of the spatial coordinates of the CT image and the surgical spatial coordinates, and solves the problem of large registration errors caused by relying on the doctor's experience for registration in the existing surgical registration process. In addition, when the above-mentioned registration method for surgical navigation needs re-registration, as long as the C-arm is used to shoot X-Ray images, the re-registration can be realized, which has stronger applicability.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a registration method, device, computer equipment and storage medium for surgical navigation. Background technique [0002] In an acetabular replacement operation, it is generally necessary to perform a preoperative computerized tomography (Computed Tomography, CT) scan on the patient's acetabulum, and perform preoperative planning on the scanned data. During the operation, in order to perform the operation according to the preoperative plan, it is necessary to correspond the posture of the patient during the operation with the posture in the preoperative CT scan data. [0003] Existing methods use the method of identifying a series of anatomical points at the acetabulum in the preoperative CT scan data and asking the doctor to find these anatomical points in the patient's acetabulum, thereby establishing the anatomical points in the CT scan data and The regist...
