Problems solved by technology

[0003] In order to solve the problem that the patient undergoes surgery after the CT3D volume data collection, the C-arm X-ray machine must be used to determine and diagnose the location of the lesion, which brings radiation risks to the patient and the doctor. At the same time, there is a C-arm X-ray machine The problem of blurred X-ray images, a method of fully corresponding fusion of preoperative CT data and intraoperative X-ray images is proposed

Embodiment Construction

[0018] Invention idea of ​​the present invention is:

[0019] A completely corresponding fusion method of preoperative CT data and intraoperative X-ray images of the present invention, such as figure 1 As shown, the 3D reconstruction of the lesion is performed using the MC algorithm based on the patient's preoperative CT3D data. The 3D reconstruction model is used as the information input, and the digital reconstruction is simulated and generated on the basis of the known dimensions of the C-arm X-ray machine to be used. For 3D image DRR images, the simulated emission source generated by the DRR image is set at the position of the real emission source of the C-arm X-ray machine, the imaging plane is set at the position of the real imaging plane of the C-arm X-ray machine, and the 3D reconstruction lesion model is located at the time of shooting. The position of the patient, so that the generation process of the DRR image can truly simulate the imaging process of the C-arm X-ra...

Abstract

The invention provides a method for fully corresponding fusion of pre-operation CT data and intraoperative X-ray radiograph, and belongs to the field of medical image processing. Three-dimensional reconstruction of a focal part is carried out by using pre-operation CT 3D data of a patient and an MC algorithm; by taking the three-dimensional reconstructed model as information input, an digitally reconstructed three-dimensional radiograph, namely a DRR (digitally reconstructed radiograph) is simulated and generated on the basis of known boundary dimensions of a C-shaped arm type X-ray machine to be applied; a simulation emission source generated by the DRR is arranged at the position of a true emission source of the C-shaped arm type X-ray machine; an imaging plane is arranged at a true imaging plane position of the C-shaped arm type X-ray machine; the three-dimensional reconstructed focal model is arranged at the position of the patient during photographing; thus, the generation process of the DRR truly simulates the imaging process of the C-shaped arm type X-ray machine applied by the system; accordingly the CT 3D data and the X-ray radiograph are fully correspondingly fused, and the DRR is used for simulating the true X-ray radiograph.

Description

technical field [0001] The invention belongs to the field of medical image processing, in particular to a method for completely corresponding fusion of preoperative CT data and intraoperative X-ray images. Background technique [0002] CT3D volume data (computerized X-ray tomography technology) is widely used in the diagnosis of the lesion location and condition of patients before surgery, and now it has become the data that must be collected before many operations, especially the diagnosis and operation of orthopedic surgery. C-arm X-ray machines are widely used in surgical operations (especially bone surgery) to determine the location of the patient's lesion and the diagnosis of the disease during the operation. The patient will be exposed to a large amount of radiation when collecting CT3D volume data. Similarly, when the C-arm X-ray machine image is collected, the doctor and the patient will be exposed to the X-ray radiation range, which will bring great harm to the pati...
