移动式C型臂X射线机图像拼接在骨科手术中的应用

背景：在脊柱和长骨骨折等骨科手术治疗中，获取骨折部位的完整骨结构图像对于监控和评价骨科术中效果具有十分重要的临床意义。 目的：探讨移动式C型臂X射线机图像拼接技术在临床骨科手术中的应用效果。 方法：对骨科手术部位的脊柱和长骨进行C型臂X射线机透视并采集2-4幅图像，经过图像拼接软件将图像多区域重叠，进行图像拼接技术处理后得到脊柱和长骨骨折内固定手术部位的1张全景图像。 结果与结论：移动式C型臂X射线机图像拼接技术处理后能在1张照片上获得脊柱和长骨骨折内固定手术部位全景图像，能较清晰、完整地显示脊柱和长骨的全景，并有助于术者在术中及时地了解和评估骨折部位的对位、对线情况，且能进行长度和角度测量，为进一步提高手术质量提供强有力的支持。

Mobile C-arm X-ray image-splicing techniques applied in orthopedic surgery

BACKGROUND:In the treatment of orthopedic surgery of the spine and long bone fractures, obtaining the complete bone structure image of the fracture part has great clinical significance for monitoring and evaluating the intraoperative effect of orthopedic surgery.  OBJECTIVE:To investigate the clinical application of mobile C-arm X-ray image-splicing technology in orthopedic surgery. METHODS:The spine and long bone in the surgical site took the X-ray C-arm fluoroscopy in order to obtain 2-4 images. The image mosaicing software was used to multiple regional overlap the images, and then a panoramic image of spine and long bone on the surgical site was obtained after treated with image-splicing technology. RESULTS AND CONCLUSION:A panoramic image of spine and long bone on the surgical site was obtained on one photo after treated with C-arm X-ray image-splicing technology, which could display the overall view of spine and long bone clearly and completely, help the surgeon to understand and evaluate the contraposition and alignment situation timely, thus measure the length and the angle. It can provide strong support for the further development of the surgical quality.
