Development of DSA Information Management and Image Analysis System Based on Java Web / 中国医疗器械杂志

OBJECTIVE@#To establish a digital subtraction angiography (DSA) information management and image analysis system to realize scientific management of DSA image information and efficient processing of image data.@*METHODS@#Based on Java Web under Windows 7 environment, a dynamic Browser/Server mode system was constructed by JSP and Servlet on the network. Eclipse and MySQL were used as development tool and database development platform. Tomcat network information service was used as application server. Matlab codes were embedded to analyze DSA image.@*RESULTS@#The system consists of five modules:image information management, image processing, image analysis, advanced retrieval and clinical data management. It may complete such process as storing, deleting, saving, analyzing of DSA image and basic information of patients.@*CONCLUSIONS@#The main interface of the system is user-friendly and easy to operate. The system will be helpful to the clinical, teaching and scientific research work related to DSA.

Research on VTK and Geomagic-based 3D craniofacial composite modeling / 中国医学装备

Objective:To construct 3D craniofacial composite model for clinical diagnosis, simulation and teaching.Methods: Collect head CT image data, and apply MC isosurface rendering method of VTK to reconstruction the 3D models of bones and the dough, then import 3D model into 3D modeling software Geomagic to repair the holes and defects, and finally complete 3D model reconstruction of craniofacial composite model by the comprehensive function of composite.Results: The experiment shows that VTK can reconstruct the 3D craniofacial model quickly, automatically, Geomagic can repair the automatic reconstruction model of defects and holes, the generated composite 3D model can fully and effectively display the three-dimensional composite structures of facial and skull. Conclusion: Using VTK and Geomagic can achieve efficient 3D modeling, and the composite model provided an effective visual reference for the face of the repair, plastic surgery and medical education.

Postoperative metabolic characteristics of islet transplantation in the treatment of type Ⅰ diabetes / 中国普通外科杂志

Objective To assess the effect of fetal islet transplantation for the treatment of Type Ⅰ diabetes. Methods The pancreatic islets from human aborted embryos were cultured and implanted into the greater omentum and omental bursa of 26 patients with type Ⅰ diabetes. The function of transplanted islets was evaluated. Results After transplantation, the exogenous insulin requirement significantly decreased (P
