Operation navigation system based on mobile DR image

Abstract

The invention provides an operation navigation system based on a mobile DR image. The operation navigation system comprises a data processing module, a preoperative operation planning module, a registration fusion module, an operation real-time guiding module and mobile DR equipment. The data processing module is connected with the preoperative operation planning module, and the registration fusion module is connected with the preoperative operation planning module, the mobile DR device and the operation real-time guiding module. The data processing module is used for acquiring a preoperative medical image, performing three-dimensional rendering according to the preoperative medical image, and establishing a three-dimensional visual virtual human body structure chart; the preoperative operation planning module is used for generating at least one operation path according to the virtual human body structure chart and embedding the operation path into the virtual human body structure chart; the mobile DR equipment is used for collecting an intraoperative medical image; the registration fusion module is used for establishing a mapping relation among a clinical image coordinate system, a mobile DR system coordinate system and an optical positioning coordinate system; and the operation real-time guiding module is used for observing the operation process in real time through the target medical image.

Description

technical field [0001] The present application relates to the field of network technology, specifically a surgical navigation system based on mobile DR images. Background technique [0002] At present, there is a lack of global patient image information in interventional surgery such as puncture ablation and minimally invasive surgery. The patient’s image information is scarce and the operation is difficult. Moreover, common clinical interventional operations are often based on CT or C-arm X-ray imaging equipment. These large-scale X-ray equipment have a large radiation dose and a large equipment volume; especially CT can only be taken in the CT room, which is generally far away from the operating room, especially the puncture and positioning of small pulmonary nodules before chest minimally invasive surgery. The operation process needs to be completed in different operating rooms, which is prone to complications. [0003] In view of this, it is an urgent problem to be solv...
