数字技术在骨科中的应用
数字技术是指利用现代计算机技术,把各种信息资源的传统形式转换成计算机能够识别的二进制编码数字的技术.目前数字技术之所以重要,就是0和1不仅能够表征各种信息,而且是计算机能够直接识别和处理的唯一数码,也是网络通信传递的数码.随着计算机和网络系统的发展与普及,数字技术已渗入人们生活工作的各个领域.在医学领域中,随着数字技术的广泛应用,促成了诸如数字解剖、数字骨科、数字医学制造、数字影像、数字化诊断与治疗等新理念.

Digital image-guided surgery to breast reconstruction
Objective We are entering a time when more and more digital images are being introduced to the operating room to enhance surgical outcomes .At the Surgical Simulation Research Lab of the University of Alberta, we developed a technology to superimpose a 3-dimentional (3D) breast model on top of the surgical site to guide a breast reconstruction procedure .Methods The breast models were created from the patient's magnetic resonance images .Our technician modified the breast model by taking data from pre-surgical scanning or from the healthy side of the breast .In the simulated environment , motion sensors were placed on the chest of the patient to capture the movements of the patient during the procedure, which were used to adjust the orientation of the 3D model to ensure a perfect mapping of the surgical site.Results Visual guidance was successfully displayed on top of the surgical site .Motion tracking captured movements of the simulated patient and was used for adjusting the 3D model in a short period of time.Conclusions Feasibility test on this innovative technology is reported in this short paper . We expect the same technology can be applied to other reconstruction surgical procedures in the future .
