As more and better communication is required with other fusion research laboratories, remote access to experimental data is becoming increasingly important in order to raise the degree of openness of experiments and to expand research results. The web-based remote data browsing system enables authorized users in geographically different locations to view and search for experimental data without having to install any utility software at their terminals. The three-tier software architecture and thin client technology are used to operate the system effectively. This paper describes the structure of the system and the realization of its functions, focusing on three main points： the communication between the participating tiers, the data structure of the system and the visualization of the raw data on web pages.展开更多

Purpose: To evaluate performance of SCB in Danish mammography screening. 3 areas were selected for evaluation: diagnostic value of SCB, performance of the Danish 7-tier mamma-radiological classifications system, DKBI-RADS, and diagnostic delay for SCB-diagnosis. Materials & Methods: Danish retrospective national cohort study including 2195 screening patients undergoing SCB. Study period: 01.01.2010 to 30.09.2012. Patients were identified from The Danish National Patient Register. Pathology-data were obtained from the Danish Pathology Database. Radiological-data according to DKBI-RADS were recorded. Diagnostic delay from clinical mammography until diagnosis was registered. Results: 173 SCBs indicated cancer;all operated with 3 cases finalized as benign. 1296 cases were determined benign with diagnostic surgery in 81 cases of which 31 were concluded pre-malignant/malignant. Correlation between DKBI-RADS and pathology diagnosis: 329 of 485 DKBI-RADS3, 227 of 450 DKBI-RADS4 were benign. 4 of 16 DKBI-RADS5 were benign. The diagnostic value of pre-malignant/malignant SCB related to results from surgery showed 94.4% sensitivity and a positive predictive value of 93.9%. Median diagnostic-time of single-biopsy was 13 days. Conclusion: The performance of SCB in Denmark is comparable to international studies regarding the diagnostic value of malignant SCB. The study indicates that DKBI-RADS classifications are not used consistently regarding micro-calcifications selected in screening-mammographies. Diagnostic delay is acceptable, subject to EUSOMA specifications, regarding single-biopsy.展开更多
