摘要
超声检查系统所呈图像中缺乏三维结构信息,且商业的医学图像分析软件价格昂贵。为此,开发一款综合病灶部位的三维模型和二维超声图像各自特征以及对应空间关系的检查系统。基于开源的医学图像处理软件、商用的电磁定位系统和超声成像系统,在局域网环境下,遵循Open IGTLink协议进行数据共享的超声检查系统。该系统主要由超声图像信息共享模块、超声图像显示模块、超声探头实时跟踪模块、2D/3D配准融合模块组成。实验结果表明,该系统可初步应用于临床教学和临床辅助诊断等领域,具有价格低廉、扩展性强、维护方便等优势。
For the traditional ultrasound system is lack of three-dimensional anatomical structures in the image information as w ell as commercial medical image analysis and visualization softw are is very expensive,develops an ultrasound inspection system w hich has comprehensive characters of the three dimensional surface model and tw o-dimensional real-time ultrasound image and their spatial relationships. This system is based on an open source medical image processing and visualizing softw are and the commercial electromagnetic tracking system,ultrasonic imaging system,w hich transmits the image and tracking data w ith each other follow ing Open IGTLink protocol in the local area netw ork. This system is mainly composed of the ultrasound image information sharing module,ultrasound visualization module,ultrasonic probe real-time tracking module and 2D /3D registration and integration module. The experimental results show that the system can be initially applied to the clinical education and diagnosis. There are three major advantages of this ultrasound inspection system,namely cheapness,scalability,maintenance.
