AI Technical Summary
Technical Problem
In augmented reality surgical navigation, the prior art registration method requires obtaining CT images and artificial spot pairing, resulting in a long surgery time and a large trauma to the patient.
Method used
By acquiring X-ray images, the positional relationship between the image acquisition device and the locator is used, combined with the pre-generated digital reconstruction radiographic image, the positional relationship between the lesion and the image acquisition device is automatically fitted to reduce manual intervention.
Benefits of technology
This method reduces the surgical time, reduces the patient's trauma surface, and improves the accuracy and safety of the surgery.

Abstract
The present application provides a registration method and device for X-ray images, including: acquiring an X-ray image, the X-ray image being obtained by an image acquisition device photographing a lesion; using the X-ray image to obtain a first positional relationship, the first positional relationship being the positional relationship between the image acquisition device and a locator, the locator being fixed around the lesion; fitting the X-ray image with a plurality of pre-generated digitally reconstructed radiographic images; using the first positional relationship to obtain a second positional relationship, the second positional relationship being the positional relationship between the image acquisition device and the lesion in the fitted digitally reconstructed radiographic image. By fitting the positional relationship between the lesion and the image acquisition device reflected in the X-ray image to the digitally reconstructed radiographic image, it is no longer necessary to manually pair the points on the wound surface and the digitally reconstructed radiographic image one by one to establish a positional relationship, thereby achieving the effect of reducing the duration of the operation and the size of the wound surface.
