Embodiment Construction

[0032] Such as figure 1 The shown a kind of C-arm X-ray sheet optical machine real-time imaging comparison method based on 3D model comprises the following steps:

[0033] Step 1: Establish the C-arm X-ray machine, body position sensing device, display screen and central server. The C-arm X-ray machine and the central server communicate through the Internet; the body position sensing device communicates with the C-arm X-ray machine through the data line, and the display The screen communicates with the central server;

[0034] Establish a 3D model module, a matrix module, an offset adjustment module and a picture comparison module in the central server;

[0035] Step 2: Construct a 3D model of the surgical prosthesis in the 3D model module, and use the 3D model of the prosthesis as a template model;

[0036] The 3D model of the prosthesis needs to contain all the information of the surface and the interior at the same time, and at the same time, all the information needs to ...

Abstract

The invention discloses a real-time imaging contrast method of a C-arm X-ray film machine based on a 3D model, which belongs to the technical field of picture processing. According to the invention, the 3D model of a prosthesis at a hip replacement surgery site is constructed, during a surgery, a position sensing device is used to determine a deflection angle. According to the obtained deflectionangle, a corresponding control prosthesis implant picture matching a current surgical angle is obtained by projection, the picture is used as the contrast of the image formed during the placement of the prosthesis during the surgery to confirm the accuracy of the placement of the prosthesis and the deviation angle, the technical problem of low imaging accuracy of the C-arm X-ray film machine is solved, The 3D model constructed by the present invention can adapt to various situations during the surgery, and obtained corresponding projection maps according to different deflection angles can be used as surgical comparison, which can ensure accuracy and reduce risk. The invention uses a projection function to attenuate a voxel matrix, which can simultaneously obtain the surface and internal information of the 3D model, and is convenient for judging the direction of implant.

Description

technical field [0001] The invention belongs to the technical field of picture processing, and in particular relates to a real-time imaging comparison method of a C-arm X-ray film optical machine based on a 3D model. Background technique [0002] C-arm X-ray machine is an imaging instrument of modern medicine, especially widely used in orthopedic surgery and other occasions. Its digital high-frequency host includes X-ray generating tubes, image intensifiers and CCD cameras for image acquisition, and workstations for image processing. The radiation output of the C-arm X-ray film optical machine is stable and reliable, and can obtain clear and rich-layer images, which are used for radiography and photography in orthopedic surgery. [0003] The existing C-arm X-ray photomechanical imaging is not very suitable for some orthopedic operations: such as hip replacement, after the hip cup prosthesis is implanted, the pelvis may tilt forward or backward , after placing the C-arm X-r...
